杭州地区某深基坑工程承压水降水设计

he excavation of the foundation pit engineering is very deep, and the confined aquifer threat the foundation. In the condition of the underground continuous wall is difficult to deep into the bottom of the aquifer to formed a fully closed waterproof, using the suspension of check water curtain and dewatering in the foundation pit to control the groundwater level inside and outside the foundation pit. This kind of condition, groundwater seepage conditions are very complicated, in this paper, using 3d seepage numerical method to design, successfully controled the groundwater level under the safety water level, ensured the safety of the foundation pit engineering smoothly, didn't infuenced the surrounding environment.
