Abstract: The construction of metro vehicle depot is affected by multiple factors such as complex geological conditions, multi-disciplinary cross-operations, and environmental sensitivity. To evaluate the construction risk of metro vehicle depots, based on the Xiaying South Vehicle Depot of Ningbo Rail Transit Lines 7 and 8, it constructs a construction risk evaluation system covering five aspects: geological foundation, structural engineering, equipment and materials, external environment, and management organization. The Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation Method are used to evaluate the construction risk. Corresponding prevention and control measures are put forward according to different risk types.
