摘　　要：在降水风险识别和因子评估的基础上,将应急预警体系引入到上海地铁M4线修复工程中,介绍了建立应急预警的目的及方法.通过对降水工程设计、施工及运行过程的研究,分析和量化了降水引起地面沉降、基坑变形等对周边环境的影响,并对风险等级进行了评判,建立了应急预警体系,提出了风险防范措施,对类似工程风险防范具有重要指导意义.Based on the risk identification of dewatering and factor assessment,an emergency warning system was introduced into Metro Line No.4 reconstruction.The purpose and method of emergency warning were established.The impacts on the surrounding environment such as land subsidence and foundation pit deformation were analyzed and quantified in the design of the dewatering project,construction and operation.The risk level was evaluated,the emergency warning system was established,and the measurements of risks were proposed.
