深基坑开挖支护变形规律及控制措施研究

Study on Deformation Rule and Control Measures of Deep Foundation Pit Excavation

以某地产基坑工程为背景,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、沉降及坑底隆起进行分析。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。

Excavation of a place as the background, using numerical simulation and field test data, for deep excavation deformation and deformation control measures are studied.Through the coMParison of calculated and measured values, retaining the horizontal displacement, subsidence and heave analysis.From the pile of embedded depth, position and stiffness, soil reinforcement, outside of the wall set and so on Foundation pit deformation control measures were introduced.
