摘要
以某城市地铁车站基坑工程为背景,借助数值模拟方法和现场实测数据,对深基坑开挖引起的变形及基坑变形控制措施进行了研究。通过对计算值和实测值进行对比,对基坑围护桩的水平位移、沉降以及坑底隆起进行了分析。从围护桩的嵌固深度、支撑位置及刚度、坑底土体加固、坑外隔离墙设置等几个方面介绍了基坑变形控制措施。
Based on the foundation excavation of subway station,the deformation of deep foundation excavation and its control measures were studied by means of numerical simulation and field observation.By comparison of the calculation values and measurement values,the authors analyzed the horizontal displacement,settlement and bottom heave of retaining piles.Measures to control foundation excavation deformation are introduced in terms of embedded depth of retaining piles,location and rigidity of supports,strengthening of bottom soil,setting of separating walls outside the excavation,etc.
