| 摘 要： | 顶管施工必然会引起周围土体的移动从而对相邻的地下区间造成危害,所以顶管穿越施工一方面必须严格控制地面隆沉;另一方面还需控制运营中的区间隧道的上浮和变形情况。采用三维有限元方法,考虑土体、区间隧道、顶管推进的相互作用,用ANSYS程序软件模拟顶管推进对区间隧道的位移影响,同时针对性地提出了相应的技术措施。

| Abstract: | The neighborhood and tunnel will be damaged by movements of soil induced by pipe jacking.While jacking,the ground upheaval and settlement must be controlled strictly;at the same time the deformation and floating of the tunnel must be controlled.Considering the coupled action of soil,subway tunnel,pipe jacking driving,with software of ANSYS,a three dimensional finite element method is used to analyze the displacements of subway tunnel caused by pipe jacking traversing construction,and some technology methods... |
