| 摘 要： | 首先用回归分析方法求得深基坑挡土墙侧向位移函数，并导出挡土墙任意剖面位移计算公式，通过地面沉降与挡土墙侧向位移之间的关系，可求出地表任意剖面沉降的最大下沉值，得出地表任意点沉降计算公式，并推导出圾表任意点沿任意方向的倾斜，曲率变形及曲率半径，最后从管道受力分析，求出允许曲率半径，两者进行比较，估计管道在基坑开挖过程中是否遭受破坏，指导施工并对地下管道采取相应措施保证其安全可靠。

| Abstract: | In this paper,a retaining wall lateral movement function is given by regression analysis in deep excavation.Displacement formula in every section is given. According to the relation between ground settlement and retaining wall lateral movement,the authors give the maximum settlement formula in every section,and also give slope,curve defromation and curve radius.Finally, by pipe force equilibrium analysis,the authors give the allowed curve radius.It is determined by comparing both to estimate if the pipes may fail. Then the construction unit takes measures to make the pipes in safety. |
