目前，我国轻轨、地铁等城市轨道交通正高速发展，但是快速、大量的城市 地铁、轨道线建设也给城市带来建设期和运营期的诸多安全问题。同时，城市轨 道交通和地铁工程项目近年来安全事故仍然是屡见不鲜，尤其是一些较大事故仍 时有发生，为预防安全生产事故提高轨道交通和地铁工程安全管理水平，要加强 城市轨道交通项目施工阶段安全管理。 本文以项目施工安全风险管理为研究主题，以CQ市轨道交通5号线施工项 目为研究案例，通过辨识该项目存在风险源，分析该项目安全管理情况，对存在 的风险进行评估，提出风险预防和控制措施，从源头控制风险，预防为主，为项 目施工管理提供参考依据，为方案制定提供有力的支撑，主要研究结论如下： 首先，CQ市轨道交通5号线施工项目安全风险有很多，主要包括：管理机 构因素、人、机、材、环境因素等五个方面的因素，并对其进行细分的18个细 分因素，通过分析按照风险源分级管控标准，将风险源划分为一级、二级、三级 三个标准，找出CQ市轨道交通5号线施工项目安全管理风险数量和分级结果， 最后，针对施工项目的安全风险，分别从五个风险因素方面有针对性地提出安全 管理措施。从完善施工安全风险管理计划、强化施工安全风险管理的实施、加强 事故后续处理及防范和加强安全风险管理的审核等方面提出CQ市轨道交通5号 线施工项目安全风险管理实施保障。 本文是以实际工程案例为依托，是科学计算、经验判断和实践总结综合得出 的成果，构建了CQ市轨道交通5号线施工安全评价方法、评价体系和安全管理 具体措施，为项目顺利建设提供依据和支撑，确保了项目安全生产，并为后续类 似工程项目提供了借鉴和经验。 关键词：城市轨道交通项目；安全风险；安全管理 Abstract Atpresent,thedevelopmentofurbanrailtransitinChinaisrapid, buttherapidandlargenumberofurbansubwayandtrackconstructionalso bringmanysafetyproblemstothecityduringtheconstructionand operationperiod.Atthesametime,safetyaccidentsofurbanrailtransit andmetroengineeringprojectsarestillcommoninrecentyears, especiallysomemajoraccidentsstilloccurfromtimetotime.Inorder topreventsafetyaccidentsandimprovesafetymanagementlevelofrail transitandMetroengineering,itisnecessarytostrengthensafety managementofurbanrailtransitprojectsinconstructionstage.
