摘要：
On the basis of expert questionnaire and the relevant specification, multi-factors influencing weight matrix was constructed by Analytic Hierarchy Process (AHP) improved in transfer matrix algorithm, and influential factors were fuzzy classified to construct the fuzzy evaluation matrix by using trapezoidal fuzzy membership function. Fuzzy evaluation analysis was carried out through multistage fuzzy comprehensive evaluation method, and verified in combination with engineering construction condition of shallow buried tunnel with large span of Zhongshan Park Station in Qingdao Metro, and four kinds of risk control schemes were established and compared on the analysis of tunnel construction risk. Results show that the model was feasible and the improved construction scheme was very effective to reduce the construction risk.
