摘　　要：对由管井、管道泵及轻型井点等构成的综合多级降水系统进行了分析,解决了承压水地区基坑不易降水的难题,指出在基坑侧壁台阶上设置地圈梁加土锚结构,增强了支护体系的整体刚度,有效地控制了基坑侧壁的变形,工程实践证明,深基坑深层多级降水土钉墙支护安全可靠。The multi-stage dewatering system which consists of tube wells, pipeline pumps and light wells is analyzed. The question that dewa- tering for deep foundation pit is difficult in the confined water area is solved. Ring beams and soil anchors are set up on the steps of deep foundation pit deep, s side, which increases the overall stiffness of supporting system and controls the deformation of deep foundation pit deep＇ s side effectively. Practice shows that the soil nailing wall with the multi-stage dewatering for deep foundation pit is safe and reliable.
