Intelligent Traffic Safety Control Technology of Highway Adjoining Tunnel and Tunnel Group

Road traffic, as a part of the entire transport system, is an important factor of social growth and development, which is necessary to create conditions for its safe operation, bearing in mind that all the benefits of this phenomenon are still paying a high price of unnecessary human suffering. In a contemporary society, there is a large number of institutions that play a role in the functioning of the transport system, but they stand out as the holders of activities and measures to improve traffic safety. Given that the number of accidents in recent years has reached a worrying level, in the interest of society is to reduce the number of accidents, or to increase traffic safety, because the consequences that the society is submitting in the form of human casualties and material damage are large. The model for the absolute traffic safety does not exist, but a permanent analytical monitoring of the status of road safety, control and regulation of traffic and taking measures to eliminate the risk factors can greatly increase the level of traffic safety.

Objective: To conduct safety evaluation of urban land in the process of goods traffic by railway transport in regions with natural hazards on the basis of system approaches. Methods: During safety evaluation, modern urban areas were considered as a complex multilevel system, concentrated mainly in large water basins and characterized by the presence of the developed railway infrastructure. Results: A complex approach of determining natural and anthropogenic hazards interrelation within the limits of an urban land was introduced. By breaking the problem of natural and anthropogenic causes of contingency within the limits of an urban land, the processes and phenomena of interrelation were considered, which, in case of integrated accounting, provides an opportunity to improve the level of forecast of land resistance to hazard occurrence. Practical importance: The developed approach and calculation data make it possible on a reasonable basis, to select measures to increase resistance, to assess the necessity in efficiency improvement of hazardous processes and phenomena monitoring, as well as to restrict the use of transportation infrastructure elements.

Control And Management

The new-type structure of "three towers of two-span" suspension bridge with the main span of 2×1080m is put to use in Taizhou Bridge. The foundation of Middle Tower adopts an extra-large underwater caisson structure with the three dimension size about 58m×44m×76m, which has been so far the deepest underwater caisson in the world. The caisson is divided into two sections, that is, Steel Caisson on the bottom and Concrete Caisson on the top. The underwater positioning, landing of Steel Caisson and the height addition construction of Concrete Caisson are of great construction difficulties and thus brought high safety risk. In this paper, Taking Taizhou Bridge as background, the safety control technology and management of underwater caisson construction is presented, which can play a good reference for similar projects.
