TBM construction risk evaluation method and system based on fuzzy mathematics theory

The invention discloses a fuzzy mathematics theory-based TBM construction risk evaluation method and system, is used for evaluating TBM construction risks under complex geological conditions, and relates to the technical field of construction risk evaluation. Selecting main factors influencing the TBM construction risk according to an analytic hierarchy process, and constructing a TBM construction risk evaluation index and system; the membership function and the weight of each evaluation index are determined based on a fuzzy mathematical analysis method, so that a definition and determination method of a comprehensive evaluation value is given based on a fuzzy mathematical theory, a grading standard of the TBM construction risk is established, finally data of each evaluation index is input, and a reasonable and correct TBM construction risk evaluation result is obtained. Therefore, the occurrence of risk accidents is reduced. And the evaluation result is further compared with the case library, and the case li
