摘　　要：针对地铁联络通道冻结法施工过程中的安全风险,利用安全风险评价法(LEC)对冻结法施工中的风险源及应对策略进行分析,采用系统性风险辨识方法对联络通道的各类风险源进行全面分类及特征分析,建立了详尽的风险源数据库,为地铁联络通道冻结法施工风险分析提供了理论基础。通过使用LEC评价法对各类风险源进行了量化分析,确定了不同风险源的危险等级,并针对于不同的风险源提出了相应的安全防范措施。研究结果表明,在地铁联络通道冻结法施工中,LEC评价法具有一定的应用价值,并可为相关领域风险预防与控制提供参考依据。In view of the safety risks in the construction process of freezing method of metro connection channel,the risk sources and countermeasures in the construction of freezing method were analyzed by using the safety risk assessment method(LEC),and the various risk sources in the communication channel were comprehensively classified and their characteristics are analyzed by using the systematic risk identification method,and a detailed risk source database was established.It provided a theoretical basis for the construction risk analysis of freezing method of metro connection channel.The LEC evaluation method was used to quantify the risk sources,determined the risk levels of different risk sources,and put forward the corresponding security measures for different risk sources.The re-sults show that the LEC evaluation method has certain application value in the construction of freezing method of metro connection channel,and can provide reference for risk prevention and control in re-lated fields.
