摘　　要：采用数值分析方法,针对杭州地铁1号线湘湖车站北二基坑的地基沉降变形与加固处理方案进行分析。通过调整基坑底加固的长度,使得湘湖站主体结构在各个区域、不同时间段的沉降变化规律能够满足地铁线路纵坡、轨道、限界等的要求,可为软土地区塌陷基坑的重建提供设计参考。Subsidence and reinforcing of North No.2 foundation pit at Xianghu Station on Line 1 of Hangzhou subway were analyzed by numerical method with the subs-idence history of the main station structure in different areas and different periods acquired.It was shown from the results that the requirements for longitudinal grade,track and clearance of the line could be satisfied by adjusting the reinforcing length of the foundation pit bottom.This work might be helpful for the reconstruction of collapsed foundation pit in soft soil regions.
