摘　　要：文中结合实际基坑工程案例,提出了“前期顶部快速大量排水,后期底部稳定轻量排水”的降水方案,并借助集水井进行降水幅度调节。结合地下水水位变化数据,发现该降水方案与施工强度时间差异性匹配度更高,能保证地下水水位在基坑施工面以下,能够控制降水速率,保证基坑边坡安全。Foundation pit dewatering is a key engineering problem that deep foundation pit engineering must face.This article proposes a precipitation plan based on actual foundation pit engineering,which involves rapid and large-scale drainage at the top in the early stage and stable and lightweight drainage at the bottom in the later stage.The precipitation amplitude is adjusted using a collection well.Based on the data of groundwater level changes,this precipitation plan has a higher degree of matching with the time difference of construction intensity.The results show that the foundation pit dewatering scheme can not only ensure that the groundwater level is below the construction surface of the foundation pit,but also control the dewatering rate to ensure the safety of the foundation pit slope.
