摘要
根据地铁施工的特点及地铁工程施工安全评价标准,比较全面、系统地构建了地铁施工安全风险评价指标体系,采用AHP和熵权结合的方法确定权重,建立以可拓法为核心的地铁施工安全风险的多级可拓评价模型.并以郑州地铁3号线为实例,确定该线路及其子系统的风险评价等级,针对评价结果提出提高地铁施工安全的有效措施,为地铁施工安全风险评价提出一种有效的评价方法.
The safety risk evaluation index system of subway construction is established on the basis,of the characteristics of subway construction and the subway construction safety evaluation standards.The method of combining AHP and entropy weight is used to determine the weight,and a multi-level extension evaluation model for metro construction safety risk based on extension method is established.Line 3 of Zhengzhou Subway is studied as an example.The risk degrees of the line and its subsystems are determined.Countermeasures are proposed to prevent accident s in subway construction.A effective method for comprehensive evaluation of subway construction safety risk is put forward.
