摘　　要：论述了安徽省枞阳县湖东二级泵站工程基坑降水的设计思路,利用干扰井群公式对各井出水量进行计算,并对坑内水位降深进行验算;采用分层总和法对坑外沉降量进行计算,评估分析降水对周边建筑物稳定性的影响。该降水方案设计可为类似地质条件的沿江泵站工程降水设计方案提供参考。A detailed introduction was made on the foundation pit dewatering design of Hudong 2nd-stage pump station at Zongyang County of Anhui Province.The interference well group formula was adopted to calculate the dewatering volume of wells.The water level fall depth in the pit was examined.The settlement outside the pit was calculated by stratified summation method to analyze the influence of dewatering on the stability of surrounding buildings.
