摘　　要：深基坑工程在降水出土阶段,如果出现水土流失现象,极易发生安全事故,造成经济损失和人员伤亡。本文结合上海滴水湖附近某工程实例,详细分析围护桩间漏水原因和抢险采用的技术方案,如拉森钢板桩封闭渗水通道、双液注浆法加固止水帷幕等,本文的研究可以为类似工程提供借鉴。In the stage of dewatering and excavation,if there is soil erosion in deep foundation pit,it is very easy to have safety accidents,resulting in economic losses and casualties.Based on a case study of a project near Dishui Lake in Shanghai,this paper analyzes in detail the causes of water leakage between retaining piles and the technical solutions adopted for emergency rescue,such as Larsen steel sheet pile closed seepage channel,double liquid grouting method to strengthen water stop curtain,etc.,which can provide a reference for similar projects.
