Risk Assessment On Mountain Area Landslide For Highway Traffic And Response Technique

Landslide invasion highway carriageway,ranging from the impact the quality of the vehicle,while buried lane,damaged transportation facilities,causing damage and vehicle cargo and passengers casualties.Mountainous Expressway located between high mountains,the terrain is very complex,probability and loss landslide disaster are enormous.Hence the urgent need for expressway landslide on traffic safety risk assessment and safety technology.A mountainous highway Landslide-prone,to have safe transportation truck caused great loss of safety.This paper focuses on the subject of landslide disasters,the basic theory landslide highway traffic impact on risk assessment,technical measures to reduce landslide impact on traffic and on traffic organization design landslide disaster three parts,in order to prevent the systematic study of landslide the impact of disasters on the high-speed traffic risk.Landslide hazard analysis mechanism for high-speed highway traffic safety and the protection of the safe operation of technology,through this study,obtained the following conclusions:(1)the landslide threat to highway traffic safety,which is rooted in instability highway landslide.Only effective governance of the landslide,the only real guarantee safe operation.Select Slides Treatment programs should be based on specific circumstances in a specific analysis,a comprehensive comparison and selection system should be.(2)based on the uncertainty of the landslide to assess the landslide hazard assessment for highway operators to evaluate the risk of fuzzy comprehensive AHP,and the corresponding improvement measures according to the evaluation results.Landslide Treatment Not once,in order to prevent landslides resurrection Treatment should strengthen the monitoring,so that the design,construction and monitoring simultaneously,to achieve dynamic information Landslide.(3)to consider the nature and structure of risk spreading rules of the road network highway landslide disaster management mechanism proposed highway traffic safety under emergency,mainly from the traffic control(information control,speed control,main control,inducing control)for traffic organization and traffic management design,including transportation organization should be based on the accident zone and into the accident zone,control zone and a buffer differentiated design.
