摘　　要：本文对管井降水从方案设计计算、成井工艺、影响因素及环境保护进行了分析,总结出一些地方性的建筑基坑降水技术经验,提出了对垂直渗透系数较小,但水平渗透系数较大的黏性土管井降水方法仍然适用的观点,对因降水而引起的环境地质问题应给予足够的重视。The design calculation, well construction, influence factors and environmental problems are discussed in the paper. Some empirical dewatering methods for the local foundation pit are put forward, which states that such dewatering methods are suitable for clays with small vertical permeability but high horizontal permeability. The geoenvironmental problems by dewatering shall be emphasized in order to guarantee the dewatering of foundation pit.
