摘　　要：建筑工程中,控制基坑地下水的有效措施就是开展深基坑止水帷幕施工,只有对止水帷幕施工方案进行科学设计,才能有效提高建筑施工整体质量,确保深基坑的施工安全。然而,如今止水帷幕施工中依旧存在一些问题,这些问题不但会降低施工质量,达不到深基坑止水帷幕设计目的,还会增加基坑风险。对此,文章以实际工程为案例进行分析,根据深基坑止水帷幕具体施工情况,对失效原因进行分析,并提出了一些抢险补救应急举措,以供行业人士参考。In construction engineering, the effective measure to control groundwater in the foundation pit is to carry out water-stop curtain construction in the deep foundation pit.Only by scientifically designing the construction scheme of water-stop curtain can the overall quality of the building construction be effectively improved and the construction safety of the deep foundation pit be ensured. However, there are still some problems in the construction of water-stop curtain, which will not only reduce the construction quality,fail to achieve the design purpose of the water-stop curtain in the deep foundation pit, but also increase the risk of the foundation pit. In this regard, this paper analyzes the actual project as a case, according to the specific construction situation of the water-stop curtain in the deep foundation pit, analyzes the causes of failure, and puts forward some emergency rescue measures for the reference of the industry personnel.
