The subway equipment construction is rather complicated, and its working scope is usually at the bottom of the ground. Therefore, common safety management mode is not suitable for subway project construction. The paper introduces three kinds of monitoring techniques in subway construction including vertical and horizontal displacement monitoring of the enclosure structure pile roof, bearing axis force monitoring and horizontal displacement monitoring of the deep layer of the enclosure structure, discusses the subway safety risk management, and finally puts forward subway construction project risk management methods, such as strengthening safety monitoring, improving alarming mechanism and emergent management, and strengthening construction field safety management.%地铁设施的建设是非常繁杂的,其作业范围通常处于地底.因此,常规的安全管理模式并不适用于地铁项目的施工中.通过对地铁施工中围护结构桩顶水平和竖向位移监测、支撑轴力监测、围护结构深层水平位移监测这3种监测技术的介绍,引出了对地铁安全风险管理的讨论,并提出加强地铁施工项目的安全监管、完善预警机制及应急管理、强化施工现场安全管理的风险管理方式.
