Study On Safety Risk Management Of Integrated Project Of Slope Engineering Survey,Design And Construction Based On The Fuzzy Analytic Hierarchy Process

With the rapid development of economy,the investment and scale of the integrated project of highway slope engineering are increasing,as well as the potential risks of the project.Therefore,how to give a better evaluation to the risk factors in the process of integrated mode construction and how to formulate a practical risk assessment system with the corresponding risk control suggestion are the core of project management.This paper establishes a safety risk fuzzy model and does a research on application based on level fuzzy AHP theory.It consists mainly of five aspects,including the domestic and foreign research situation of slope engineering integration project,risk management theory,risk assessment methods,example application and project risk countermeasures and suggestions.First of all,the risk research status of integrated highway project and the related contents of integration project risk in slope engineering are summarized.It shows that the current research on project risk focused on theory and lacked in application research.Based on the research,the four main factors that affect the risk of integrated project of slope engineering are summarized,and the detailed list of influencing factors is listed.After that,a model of the importance degree of each factor is established.Then,the risk assessment system of integrated project of slope engineering is established based on the fuzzy analysis of mathematical method,the analytic hierarchy process(AHP)and system engineering methods.The general steps are as follows: to establish the safety risk index system,to calculate the weight of the index system of each layer based on the AHP method,and to carry out comprehensive evaluation based on the fuzzy theory.Therefore,a whole set of safety risk assessment process for the integrated project of slope engineering based on the fuzzy theory can be obtained.Finally,the application process of the proposed method in the specific project is illustrated by a specific example.Through the example,a safety risk assessment system is established for the investigation,design and construction integration project in highway slope engineering based on the theory of Fuzzy AHP theory.The evaluation index system is comprehensive with the clear direction and distinct hierarchical classification.The rating standards need only simple quantitative calculations and have a good performance in the practical project as far as possible.According to the risk assessment system of the integrated project of the highway slope engineering,the investors can understand the importance of the risk factors of the integrated project of slope engineering,and then formulate the corresponding risk control measures.
