摘　　要：通过对某项目二期工程基坑开挖施工阶段坑内浅层滞水产生的原因进行分析,讲述了深基坑浅层滞水的降排水处理方法,采用增设降水井点、局部轻型井点二次降水,并结合坑内集水明排的综合降排水方法,在短期内有效地解决了基坑内浅层滞水问题。总结的降排水施工方法可为类似项目提供借鉴。Based on the analysis of the causes of shallow stagnant water in the pit during the foundation pit excavation construction stage of phase II project of a project,the dewatering and drainage treatment method of shallow stagnant water in the deep foundation pit is described.The problem of shallow stagnant water in the foundation pit is effectively solved in a short time by adding dewatering well points,secondary dewatering of local light well points and combined with the comprehensive dewatering and drainage method of open drainage of water collection in the pit.The summarized dewatering and drainage construction methods can provide reference for similar projects.
