摘　　要：结合上海市静安区闸北广场项目实践,针对基坑降水要求,采用了组合式承压水控制技术来处理地下水。通过基坑降水数值模拟以及地面沉降预测,有效地减少了降水可能造成的对周围环境的不良影响。总结的成功经验可为类似工程参考。Combined with the practice of Zhabei square project in Jing'an district of Shanghai,combined confined water control technology is adopted to treat the groundwater according to the requirement of foundation pit dewatering.Through the numerical simulation of foundation pit dewatering and the prediction of ground subsidence,the possible detrimental effects of dewatering on the surrounding environment are effectively reduced.The successful experience summarized can be used as reference for similar projects.
