Research On The Risk Assessment Of The Highway Slop Anti-seismic Safety

China's vast land is a very complex terrain and in an active seismic zone in the mountains along the slope during construction of the project will form and meet a lot of slope problems.Compared with the traditional methods of analysis,risk analysis theory considers the uncertainty factors in the engineering.The combination of probability and risk,provides a new scheme for the evaluation of highway slope engineering.The research of highway slope risk assessment theory is the key to solve this problem.This paper aims at the research of highway slope seismic safety risk assessment theory,and is verified by an engineering example,the specific contents are as follows:1)System to collect and analysis of the current domestic and international relevant risk evaluation method of highway slope,the slope stability analysis of research methods and research aspects,summarizes the current research on problems of highway slope in risk assessment,puts forward solving methods.2)Through the research of risk assessment theory,combined with the actual situation of the risk analysis of highway slope,choose the analytic hierarchy process and fuzzy comprehensive evaluation method combining way,establishes the risk assessment system of safety of slope of highway.3)The Wei Pu highway slope as an example,this paper established the system used to evaluate the risk of the highway slope seismic safety of slope,and then determine the level of risk,and provides theoretical support for the management and maintenance of highway slope.4)Consistent with the evaluation results obtained by evaluation system of highway side seismic safety and the actual observation,verify that the evaluation system is correct and practical,and provides a new idea for seismic safety evaluation of highway slope.
