Bridge to Russian island description. Russian bridge in Vladivostok: technical features and interesting facts

In Vladivostok, a bridge connecting the mainland with Russky Island sagged and deformed several stays. Drivers were the first to notice the fault on the new bridge on Wednesday. See the damage on high altitude, especially from a passing car, is not easy, but the townspeople managed to do it before the specialists. One of the drivers, moving to Russky Island, in particular, saw that the second shroud from the beginning of the bridge and the fourth on the left sagged and took on a wave-like shape.

Checking this information, the correspondent of the vl.ru edition went to the bridge and counted that nine red guys have a wave-like shape.

The regional administration stated that the bridge to Russky Island is operating normally, changes in the outer shell of the cables do not affect the quality and safety of the operation of the bridge, and that USK MOST OJSC, which maintains the bridge, continuously monitors it. According to the company's specialists, the sagging of the cables is due to weather conditions and is a regular situation - this happens often, and "bridgers know about it."

USK MOST said on Thursday that the bridge's design was affected by the weather. “Deformation of the outer shell of the cables of the Russian Bridge occurred as a result of a change in the temperature regime environment- said the head of the press service of the company Alexei Skorobogatko. “However, this absolutely does not affect the reliability, durability and safety of operation of the bridge. Due to the temperature difference and free space, the deformation of the shell can be observed with the naked eye, but it performs only a protective and decorative function.

The cable-stayed bridge to Russky Island was built for the APEC summit in 2012 and holds the world record for the length of the central span, which was 1,104 m, and the height of the pylons, 324 m. 32.5 billion rubles were spent on its construction.

The stays were manufactured and supplied for the construction of the bridge by the French company Freyssinet (Freyssinet International and Company), which eventually acted as a consultant to the Russian contractor. In January of this year, about the disappearance at the bridge construction a large number scrap metal in the amount of 96 million rubles.

In KU "Federal Administration highways « Far East(FKU "Dalupravtodor") stated: "No violations in the operation of the cable-stayed system on the bridge across the Eastern Bosphorus Strait in Vladivostok have been identified." “In accordance with the contract for the maintenance of the bridge, the cable-stayed system as part of other structures of the bridge is subject to daily inspection,” says the report received by the editors of Gazeta.Ru. - The light wavy surface of the shells of guys No. 2 and No. 6 is their design feature and does not affect the strength, reliability and durability of the guys, as well as other structures of the bridge crossing. The entire cable-stayed system was put into operation without any comments or deviations from the requirements of the project documentation.”

Igor Kolyushev, general designer of the entire facility, general director of ZAO Institute Giprostroymost St. Petersburg, earlier on a specialized resource Rosmost described similar movements of the guys:

“Fatigue phenomena in the stiffening beam and guys have not been studied enough. The probabilistic wind, combined with live loads, can affect the design of the bridge in the most unpredictable way.”

Bridge experts who erected the nearby bridge in Vladivostok believe that the sagging of the cables is unlikely to threaten disaster. “The bridge is a flexible structure, the span can walk, and the tension of the cables can change, so some change in the shape of the cables visible to the eye may not be something dangerous,” Alexander, deputy director for technical issues at CJSC, told Gazeta.Ru TMK, which built another cable-stayed bridge in Vladivostok. “The state of the guys is strictly monitored by the sensors of the monitoring system, so if something really out of the ordinary happened, the bridge would already be closed and specialists would work to fix the problem.”

However, the bridge builder added that so far nothing of the sort has happened to the neighboring bridge across the Golden Horn Bay, also built for the APEC summit. “In general, if some shroud sags, it will simply be pulled up,” Lebedev reassured.

Traffic on the bridge to Russky Island was officially opened by the Prime Minister on July 2, but a few days after the head of government left, the bridge was closed and reopened only in August. However, after just a few weeks, on August 25, traffic for ordinary motorists was again closed due to preparations for the summit and the event itself.

The construction of the bridge to Russky Island is carried out within the framework of the subprogram "Development of the city of Vladivostok as a center of international cooperation in the Asia-Pacific region".

The bridge to Russky Island will be one of the largest cable-stayed bridges in the world, with a central span of 1,104 meters that will set a record in world bridge building practice.
This bridge will have both the highest pylon and the longest shrouds.

Bridge parameters:

Vladivostok, November 8 - AiF-Primorye. The bridge to Russky Island in Vladivostok has been criticized from the very beginning of construction. Some experts questioned the feasibility of such a grandiose project. Another "fly in the ointment" was added by Alexei Mikhailov, an analyst at the Center for Economic and Political Research (EPIcenter).

Why is it needed?

The cable-stayed bridge (like its Golden “brother”, which connected the city center with Cape Churkin) to Russky Island was built as part of Vladivostok’s preparations for the APEC summit. The building is unique. After all, the Russian Bridge (this is its official name) has the largest span in the world among cable-stayed bridges, 1104 meters long, and the first pylons in height - 324 m.

Economist Mikhailov gives other impressive figures: the cost of construction is about $1 billion. The same amount was spent on the access road (to the airport and the city).

“This cable-stayed bridge is actually very beautiful, floating in the air with a central span of more than 1 kilometer at a height of 70 meters, which is supported by two pylons 324 meters high. Probably, he is grandiose in engineering solutions. And it will certainly become a new symbol of Vladivostok now. That's just ... why is it needed? ”, The expert asks.

The analyst's main argument "against the bridge" is the same as that of many critics of the structure - it has a small capacity, and the population of the island is too small for such costs.

“A bridge with a capacity of 50,000 cars a day leads to a small Russky island with a population of 5,000 people. And even those mostly poor fishermen who live in barrack-type houses do not have cars,” says Mikhailov.

In contrast to this criticism, the Vladivostok authorities have repeatedly stated that the bridge was built, among other things, for the development of the island, the program of which includes the construction of many large facilities and the creation of infrastructure for 150,000 people.

The bridge "does not pay off"

"What's next with Fr. Russian? Now there are the same 5,000 residents without cars. Hand on heart, tell me, was it really worth spending $ 2 billion to access the beaches by car? Is there no way to get there by ferry? After all, every two hours he walks and even transports cars, it’s not so expensive, ”the expert continues.

The development of tourism, the construction of new housing on the island is one thing. But perhaps the main argument in favor of the feasibility of the bridge was the FEFU under construction on the same island. After all, it was planned that the united university would become the largest educational institution countries and even the world. Students from all over the world will come there to study, and the best foreign teachers will teach. However, the contractor did not have time to complete the construction of the FEFU buildings. And the great "relocation plan" failed, and the students remained on the mainland, at least until the building was completed. Now only out-of-town students live on the island, who go to classes in the city every morning.

To this all can be added the absolutely undeveloped road infrastructure of the island. After you drive off the bridge, you get to the real " Russian roads”, after passing through which it is necessary to resort to the services of an auto repair. Therefore, most of the townspeople do not dare to go there. And taxi firms raise prices for trips to the island - up to 1 thousand rubles from the center of Vladivostok.

Alexey Mikhailov compares the bridge to Russian with his "colleague" Golden Gate in San Francisco, USA. Just not in favor of the first.

“Basically, they are similar. But the Golden Gate was built 75 years ago, it is paid and actually passes 120 thousand cars a day. This bridge literally earns half a million dollars daily. And the Russian Bridge is free and how much will it actually pass per day after the APEC summit is over? A couple of thousand cars? Or maybe a couple of hundred? ”, The expert writes.

However, it is worth noting that neither the bridge builders nor the authorities of Primorye share the economist's opinion.

“This will be a comfortable area of ​​Vladivostok, very convenient for living. Children will be able to go to school here, then to the university - and there will be no need to travel anywhere. As for the other territory of the island, it is planned to leave it under the tourist and recreational zone, - believes Governor of Primorye Vladimir Miklushevsky. - Only the coast will be built up - we are talking about boarding houses and rest houses. Still, the nature of the island should be preserved as much as possible for posterity.

“Look at any photograph, tourist brochure: if there is a bridge in the city, then it will certainly be on them. The bridge is a kind of monument, an architectural decoration of the city, an achievement of its inhabitants. San Francisco - Golden Gate, New York - Brooklyn Bridge, Hong Kong - Stonecutters Bridge - speaks his mind Alexey Baranov, Director of the USK MOST branch in Vladivostok. - And one more indisputable advantage, purely practical. Having connected the mainland with Russky Island, the bridge opened up new prospects for development. Many cities in Russia, including Vladivostok, suffer from a heterogeneous style: in different periods, under different governments and cultures, they built differently and did not always care about compatibility. And the facade of the city in a good way should be planned once and for all, only then it will be beautiful. Of course, the city cannot afford the restructuring of existing quarters. But in Russian there is a chance to start from scratch, resulting in a large and harmoniously built-up area, very promising for development.”

By the way

The issue of building a bridge to Russky Island was raised in the first half of the 20th century. The first project was completed in 1939, the second - in the 1960s. However, neither one nor the other has been implemented. At the beginning of October 2007, NPO Mostovik won a tender for the design of a bridge crossing to Russky Island. JSC "USK MOST" acted as the contractor. The construction of the bridge began in 2008, on July 1, 2012, Prime Minister Dmitry Medvedev opened the working traffic on the bridge, and a month later, on August 1, the bridge was opened for personal transport.

How it all started

The issue of building a bridge that will establish regular communication between Vladivostok and Russky Island was raised in Tsarist Russia. All this time at local residents there were only two possible options for crossing to the mainland: by ferry, as well as on foot through the layer of ice that covers the strait in winter.

The first engineering project of the Russian Bridge was developed back in 1939. It was assumed that the structure would be wooden and would connect Cape Tokarevsky and Helena Island. Later attempts to build a structure (70s, 80s) remained in the development stage.

AT last time the need to create a bridge across the strait was discussed in connection with the preparations for the APEC summit. As part of the investment project, Russky Island was supposed to be turned into the largest center of international cooperation, and for this it was necessary to establish transport connection with the mainland.

Despite the fact that the upcoming event was accompanied by another economic crisis, the government decided not to abandon the decision. Moreover, the construction of such grand object, like the Russian Bridge, was supposed to give a tangible impetus to the revival of the Far Eastern region.

Design and construction

In 2007, the research and production association "Mostovik" received permission to create a project for the future bridge. Among several options proposed by the engineers, preference was given to the cable-stayed design. The foundation for the future construction was to be pylons, which would "bear" the main weight of the bridge. A well-thought-out system of cables (cables) should have been responsible for the distribution of the load. Metal cables were attached to different points of the pylon in the form of a fan, giving the structure maximum stability.

The main difficulty in this was the too short time allotted for the design of the Russian Bridge. It was necessary not only to develop a site plan, but also to take into account such negative factors as unstable weather, high seismic activity in the region, as well as seasonal temperature fluctuations. In addition, we had to take into account the inevitable bulk of ships passing through the strait, and at the same time the half-meter ice crust that forms on the water surface in winter. However, despite all the difficulties, the project was fully completed and handed over to construction companies in 8 months, which became a kind of world record.

Work on the construction of the Russian bridge began in September 2008. The construction was entrusted to the general contractor USK MOST, the creation of the cables was undertaken by the French company Freyssinet, and the Russian team of MT Electro specialists took up the lighting project.

Especially to reduce the load on the structure, a special type of cables with a ribbed surface was created. It was assumed that the network of “grooves” applied to the cables would remove raindrops, as well as air currents, thereby increasing the endurance of the Russian Bridge.

The construction of the structure was sometimes carried out in extreme conditions. Sharp gusts of wind, low temperatures - all these negative factors were constant companions of the installation work. As an example, it suffices to cite the fact that the last consoles that were supposed to close the structure were installed at night. Since, under the influence of solar radiation, the parameters of metal blocks can change their characteristics, and maximum accuracy is required for joining the grooves, the work was postponed to night time.

Russian Bridge Records

• The structure has the highest pylons (bearing structural elements) - 324 m.
• Compared to all existing similar structures, the Russian Bridge has the maximum cable-stayed span (1104 m).
• During the construction of the bridge, the longest guys (cables attached to the pylons) were used - from 135 to 580 m.

The total length of the structure, including overpasses, is 3100 m. The length of the bridge itself is 1885.53 meters. On August 29, 2012, the structure passed the strength test with honor, having withstood the devastating pressure of the Pacific Typhoon Bolaven. And a few days later, on September 2, 2012, the official opening of the working movement on the carriageway of the Russian Bridge took place, which was attended by D. A. Medvedev. The solemn event was timed to coincide with the day of the city, marking it with festive fireworks.

Grace incarnate

Despite the fact that the main function of the Russian Bridge is a transport connection between the island and the mainland, the aesthetic characteristics of the most modern landmark of Vladivostok can cause genuine admiration. A fantastic view of the structure opens at night when the architectural lighting is turned on. Professionally built lighting creates an optical illusion of flight. The bridge seems to hover over a dark strait.

The futuristic appearance of the Russian Bridge is complemented by the guys themselves. Painted in the colors of the Russian tricolor, they give the composition a special, unique flavor and extraordinary solemnity. To fully appreciate the true power of architectural design, it is enough just to ride from the mainland to the island. Only when driving along the motorway leading through the bridge, you can truly feel the solidity and amazing beauty of this unique structure.

• Initially, three projects for a cable-stayed bridge were proposed.
• The structure is closely monitored, and its condition is monitored around the clock by satellite systems.
• The image of the Russian bridge can be seen on banknotes with a face value of 2000 rubles.

How to get there

The address of the Russian bridge: Vladivostok, the East Bosporus Strait, st. Velvet.

The easiest way to get to the main seaside attraction is bus trip. Routes No. 15, 22, 29, 74 and 76 go through the Russian Bridge. A more comfortable and, accordingly, more expensive option is a taxi.
