摘　　要：随着城市地下综合体、轨道交通和海绵城市等实体和概念的发展,建筑空间日益向地下延伸,地下水控制在施工中的地位越发突出,其对环境和水安全的影响也越来越受到重视,特别是对多层地下水逐层研究控制方案,优先选用截水帷幕结合少量降水的组合式控制方法成为深基坑设计的发展方向。通过对实际案例分析,对上层地下水采用落底式帷幕进行阻挡,对下层地下水采用悬挂式帷幕方法进行控制,并对悬挂式截水帷幕基坑内涌水量计算的经验系数进行研究和统计。With the development of the entities and concepts such as urban underground complex, rail transit and sponge city, the building space extends deeper to the underground, groundwater control becomes more and more prominent in the con- struction, and its influence on environment and groundwater safety is more and more important, especially for the multilayer groundwater research and control scheme. It is the development direction of the deep foundation pit design that curtain of water cut is selected with a small amount of dewatering method. Based on the analysis of the actual cases, the upper ground water is obstructed by the curtain to the bottom, the suspended curtain is used to control the underground water, and the empirical coefficients of the water outflow is studied and counted in the foundation pit of the suspended curtain.
