摘　　要：限于目前技术水平,基坑降水很难计算准确,往往采用半理论半经验进行设计。非均质土层条件下基坑降水设计计算更是工程技术人员面临的一大难题。通过某新建电厂堆煤区地下传送廊道基坑降水设计工程实例,探讨非均质土层条件下基坑降水设计与施工。It is well known that confined to present technology level,it is very hard to accurately calculate dewatering of foundation excavation and usually by half-theories and half-experience method.Design and calculation of dewatering in foundation excavation in non-homogenous soil is more difficult for engineers.In this article,the authors discuss this problem by an engineering example of dewatering design of foundation excavation on some underground transmission corridor.
