摘　　要：为解决南京河西及江北新区长江漫滩区深基坑工程地下水控制问题,通过场地抽水试验确定场地地层综合渗透系数,以确定降水井布置数量,结合降水井结构优化、坑外地下水回灌及智能化实时监控等技术,为后续施工阶段的地下水控制提出了可行性指导方案。该地下水控制设计及应用的研究结果可为类似深基坑地下水控制提供技术指导,也可为基坑地下水控制的施工管理运行提供一定的指导。To solve the problem of groundwater control in deep foundation pit projects in the Yangtze River floodplain area of Nanjing Hexi and Jiangbei New Area,the comprehensive permeability coefficient of the site strata is determined through site pumping tests,and the number of drainage wells is determined.Combined with the technologies such as optimizing the structure of drainage wells,groundwater recharge outside the pit,and intelligent real-time monitoring,a feasible guidance scheme is proposed for groundwater control in the subsequent construction stage.The research results of groundwater control design and application can provide technical guidance for similar deep foundation pit groundwater control,and also provide certain guidance for the construction management and operation of foundation pit groundwatercontrol.
