Abstract

In order to reduce hidden danger of subway accidents and prevent the occurrence of accidents in foundation excavation of subway stations, safety evaluation is applied. This paper proposes the fuzzy comprehensive evaluation method that is combined by qualitative analysis and quantitative analysis. Based on the frame of safety evaluation system in foundation excavation of subway stations, it constructs the target system, and analyzes the appraisal factor. The result shows that by taking the fuzzy mathematics theory as a basis and considering various factors of safety, the fuzzy comprehensive evaluation method in foundation excavation of subway stations is established. With experts investigating and determining each factor's weighting, reasonable and comprehensive evaluation of foundation excavation of subway stations are made. By applying the fuzzy theory to evaluate the safety about foundation excavation of subway stations, it may conclude with the safety classification, it becomes more evident whether the accidents in foundation excavation of subway stations will appear or not, then improvement can be made, based on the evaluation situation.
