在坑底存在有承压水的深基坑，当承压水头压力大于上覆隔水层的重力时，为防止隔水层发生渗透变形破坏，常采用减压井的措施。文章时此作点初步探讨。①渗透变形在深基坑底引起的破坏形式；②降低承压水头——减压井的计算分析方法探讨；③减压井设计计算的步骤及计算例题。

In the den greater than on the deformation damage there are confined aquifer of deep foundation pit, when the pressure head's pressure is overlaying water-resisting layer of heavy, to prevent water-resisting layer seepage occurred, often using the measures of reducing pressure wells. In this paper, it explains some preliminary discussion. ①seepage deformation in deep foundation pit bottom cause damage form; ②to reduce the pressure head the computational expressions of relief wells; ③relief wells, design calculation steps and calculation examples.
