Modern ferry crossing as an important element in the development of eco-tourism in Sakhalin

Abstract

The Sakhalin region and its ecology, natural features and federal reserves with natural ecosystems, has a high potential in ecotourism, and therefore the problems of operating bridge span structures of the ferry crossing connecting the island with the mainland are becoming increasingly important. This is due to the fact that the traffic flow at the ferry crossing, including off-farm transportation of agricultural goods, has increased significantly. Consequently, the load on the bridge structures has increased. In addition, natural factors play a significant role in the operation of the structures. Therefore, the issue of the durability of bridges has several generalized components, including the mechanical wear along with moral and physico-chemical wear. The paper deals with the topic of the correct and uniform distribution of high load bearing between structural elements of large-span structures, since under the influence of the natural gravity of the structure and the influence of external factors, dangerous damage can occur. As a research task, the authors determined an attempt to assess the load of the lifting mechanisms located on the abutments of the intermediate supports and serving to set the spans in the required position. In case of increase in the mass of spans, overcoming the resulting imbalance can lead to a noticeable increase in the required power of the drive of the mechanisms.
