The Tunnel Research Of Risk Assessment And Disaster Prevention And Treatment In The Tai Yuan To Jia Xian Highway

Along with highway construction in our country,especially the highway development of the mountainous area, large-scale building of mountains highway tunnel, leads the risk accident for tunnel construction to rise year by year. More and more people pay attention to the risk issues of tunnel construction, so conducting effective risk evaluation, disaster prevention and control work for tunnel construction, establishing appropriate safety risk assessment system, and actively responding to high-risk problems during tunnel construction are inevitable.This paper relying on Old Longshan tunnel on Tai Jia highway, from the perspective of risk assessment in tunnel construction, combined with the disaster management in tunnel construction, studies problems of the risk and disaster prevention and controlthe in tunnel construction process.1) Based on the analysis and study of the risk in tunnel construction, mechanism as well as causes of the risk, this paper reveals the general rules of the occurrence and essence of risk. Besides, combined with the characteristic of old longshan tunnel, this paper puts forward the corresponding suggestions for risk management in tunnel construction.2) Risk assessment is the premise of safety in tunnel construction. Combined with the characteristics of construction projects, using with the extension comprehensive evaluation method for tunnel construction risk assessment of Old Longshan tunnels, detailing the primary risk level segment of tunnel, then according to the level section of tunnel risk, this paper puts forward the prevention measures for risk in tunnel construction.3) Combined with disasters treatment plan for old longshan tunnel, according to the relevant supporting state data obtained from monitoring and means of finite element simulation, this paper evaluates the plan and effects of the disaster management.
