摘要
目的减少地铁工程事故隐患,防止地铁车站基坑工程安全事故的发生.方法根据系统工程学原理,提出采用定量与定性分析相结合的地铁车站基坑工程安全性评价方法———模糊综合评价法.依据地铁车站基坑工程安全评价体系的基本框架,构建地铁车站基坑工程的指标体系,并对评价因素进行分析.结果以模糊数学理论为基础,建立地铁车站基坑工程的模糊综合评价法,能够综合考虑影响地铁车站基坑工程安全性的各方面因素,通过专家调查确定各因素权重,从而对地铁车站基坑工程的安全性进行较为全面、合理地评价.结论应用模糊理论对地铁车站基坑工程安全性进行评价,可得出地铁车站基坑工程的安全等级,使得地铁车站基坑工程事故的发生与否趋于明确化,并依据评价情况进行改进.
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.
