The Subway Engineering Risk Assessment Based on Fuzzy Comprehensive Evaluation

Abstract:

Characteristics of the subway project is complex, concealed, lot of potential risks. Aiming these features, in order to reduce the risk of the project and improve the rationality and accuracy of subway risk assessment, the main risk factors in the subway are analyzed and identified by methods of expert investigation and checklists, and the risk index system is established, based on research of the subway construction risk mechanism. Then the membership of each evaluation factor is determined by the expert experience method, and the weight of each risk factor is determined through the method of analytic hierarchy process (AHP). Eventually, the subway engineering risk assessment model is established based on the fuzzy comprehensive evaluation method. Finally, the project example verifies the rationality of the risk assessment model.
