| Abstract: | 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. |
