Transport Construction of the Mainland—Sakhalin Island

Shestakova, Ekaterina / Novikov, Anatolii / Antonyuk, Anatoly / Kurchanov, Pavel

The article discusses issues with a high degree of preparation for the design, construction and operation of artificial structures of transport infrastructure, in the difficult climatic conditions of the Sakhalin region with a long winter season with abundant winter precipitation, hazardous deposits of ice and ice freezing, and taking into account high-seismic activity territory. The authors presented the results of work on assessing options for the development of transport infrastructure by providing a message to the mainland of the Russian Federation and Sakhalin Island through the Nevelsky Strait, with the rationale for a solution to the problem of a transport transition and an assessment of the tunnel-bridge alternative. The effectiveness of the solution is predetermined in the use of two main options: a tunnel (or a tunnel-dam) and a combined version of a tunnel-bridge; two static schemes taking into account the uniqueness, III category of complexity, heterogeneity of the structural-tectonic conditions of the transport transition for the mainland and island parts. When designing transport facilities for Sakhalin, specific features should be taken into account, namely, difficult climatic conditions, the peculiarity of the economic and geographical position (Russia’s only region on the islands, proximity of Japan and other rapidly developing Asia-Pacific region), the current structure of the economy, the uniqueness of the resource potential (biological and hydrocarbon resources of the shelf are of regional and national importance), economic and social development, integrated development and development the non-raw material base of the Far East, industrial development of the regions, major logistic schemes and the prospect of total cargo turnover (The Eurasian Land Bridge) and the potential for the development of the tourism industry. This could change the economic picture of Sakhalin and contribute a big share in the economy of Russian. The rich natural, cultural and historical potential of Sakhalin Island has not yet been fully utilized in the development of international and intraregional tourism. The use of innovative technologies to solve engineering problems will be focused on the requirements for modern artificial structures: reliability and durability, safety and efficiency throughout the life cycle. The choice of the best option, taking into account the alternatives “tunnel-bridge” will be carried out on the technical and economic indicators of total, construction and operating costs, including the payback period, the cost of emergency situations, seismic and environmental safety.
