摘　　要：结合某基坑降水工程中遇到的实际问题,即同一个基坑中不同的开挖深度导致降水深度不同的问题,为保证深基坑开挖安全,采用不同的止水帷幕延伸长度L,取L为5.0、10.0、15.0、20.0、25.0、30.0 m,运用Visual MODFLOW软件对止水帷幕进行设计计算,分析降深等值线图,以满足设计要求,最终得出L为20.0 m较合适,取L为25.0 m可进一步保证安全,以此指导基坑止水帷幕设计。In this paper,combined with the practical problems encountered in a foundation pit dewatering project,that is,different excavation depths in the same foundation pit lead to different dewatering depths.In order to ensure the safety of deep foundation pit excavation water curtain with extension lengths of L=5.0,10.0,15.0,20.0,25.0 and 30.0 m are taken.Visual MODFLOW software is used to design and calculate the waterproof curtain,and the contour map of drawdown is analyzed to meet the design requirements.Finally,it is concluded that L=20.0 m is more suitable,and L=25.0 m can further ensure safety.To guide the design of foundation pit waterproof curtain.
