随着高层建筑、深基坑的不断增加，在旧城区施工降水，引起邻近建筑、管线、路面开裂下沉的现象屡见不鲜。本文结合某大型深基坑工程降水施工，介绍受潜水与承压水作用下深基坑降水的设计思路、施工工艺、实施效果。

Deep Foundation Pit Filling Water and Rainfall Construction under the Complicated Environment Water

With an increasing number of high-rise buildings and deep foundation pit. In the old town construction pre-cipitation, the phenomenon that causes the adjacent building, pipeline, and road noodles sinks common occur. This paper combines with a large deep foundation pit engineering cons-truction and introduces the deep foundation pit dewatering design idea, construction technology and implementation effe-ct suffer the water and confined water.
