上海某广场基坑抽水试验分析

Analysis on the square foundation pumping test in Shanghai

以上海某广场为例,通过现场抽水试验确定基坑挖影响深度范围内地下水的分布特征、渗透系数和抽水影响半径等重要的水文地质参数,为基坑挖和降水工程提供设计依据与研究基础。

Abstract： Taking the square in Shanghai as an example, the paper determines underground water distribution features, permeability coefficient and pumping influencing radius and other important hydrological parameters within foundation excavation influencing scope through in-situ pum- ping test, which has provided design basis and research basis for foundation excavation and dewatering engineering.
