摘要
通过对顶管施工过程中的地层变形进行三维有限元模拟,探讨了顶管横向和纵向地层随开挖掘进面前进的变形规律,并对不同深度地层变形进行了比较,得出一些结论,为采取措施减小地层变形提供了借鉴。
In this paper, a 3D nonlinear finite element model for simulating pipe-jacking is proposed. The distributions of soil displacement around the pipe and on the ground surface associated with the pipe-jacking operation are analyzed in detail. According to the comparisons of different depth settlement results, some useful conclusions are drawn. And at the same time, the quantitative results and some discussions can make decisions on reduction of stratum deformation.
