Fuzzy Comprehensive Evaluation Method And Ahp Based Research On Safety Risk Evaluation Of Subway Station Construction

The city's rapid development has promoted the subway construction,the subway's development has promoted the city's development,and has satisfied the citizen to travel the need.Subway safety is very important.Subway operation is to realize the goal of transportation safely.The construction safety of subway station is an important part to ensure the safety of subway transportation.Improving the construction safety risk analysis system of subway station can effectively control the construction safety,and the effective quantitative construction risk evaluation model can more accurately evaluate the construction risk,so as to carry out precise management and control of construction safety.This paper from the point of view of the operation of the subway station to analyzes the safety problems of the subway,studies the safety risk prevention and control system of the subway construction in detail,and constructs the construction safety risk prevention and control system,quantitative Construction Safety Risk Analysis model.Subway station construction content is diverse,professional cross-fusion complex.Starting from the construction content,this paper analyzes the main risk points of subway station construction.The four factors of subway construction are further analyzed and discussed from the perspectives of human,machine,environment and pipe,so as to improve the construction safety risk analysis,evaluation and prevention and control system theory construction from different stages and angles,and construct the construction safety risk management and control system.This paper focuses on the construction of subway construction safety risk quantitative evaluation model.through the construction safety risk factor analysis,combing the construction risk factor analysis tree structure,build risk evaluation goal,evaluation standard and evaluation index,using the analytic hierarchy process(ahp)to construct the construction safety risk analysis weighting matrix,due to the large data failed to effectively utilize,insufficient construction risk data statistics,this paper USES expert evaluation method,build a complete evaluation matrix based on fuzzy comprehensive evaluation method of membership function,a weighted matrix and evaluation matrix,realize half quantitative analysis of the construction risk assessment results,and analyzes the application of quantitative models.
