摘　　要：上海中心大厦位于上海陆家嘴金融贸易区中心和上海市地下第一、二、三承压含水层连通区,基坑深达31 m,周边环境复杂,含水层层顶埋深28 m,降水周期长达140 d以上。基坑降水经优化设计,精心施工,科学运行,达到了既降低开挖区域水位又保护周边环境险情防治的目的。Shanghai center building is located at Shanghai Lujiazui finance and trade zone where the first,second and third underground confined aquifers are connected directly.Its pit depth is 31 meters,and the surrounding environment is complex.The top layers of aquifers is 28 meters deep,dewatering time is up to 140 days.Due to optimized design and careful construction,the dewatering achieve the objective of reducing the excavation of the danger and protect the surrounding environment.

关 键 词：基坑降水 承压水 地面沉降
