Abstract: In order to comprehensively and objectively evaluate the risks faced by the underground comprehensive pipe corridor with large investment, wide coverage and long operation cycle, this paper takes a pipe corridor in Beijing as the object, based on the whole life cycle theory, identifies the risk factors in six stages of the whole life cycle of the pipe corridor, and establishes a risk index system consisting of 6 second-level and 43 third-level risk indicators. The comprehensive evaluation model of pipeline corridor risk based on AHP and Fuzzy was established, and the results were verified by weighted distribution method. The research results show that the overall risk of the whole life cycle of the studied pipe gallery belongs to the medium risk, of which the risk of abandonment stage is the highest, followed by construction and completion stage, operation stage, design stage, bidding stage and decision-making stage, and put forward targeted management measures.
