ANALYSIS OF THE DISPLACEMENTS OF UNDERGROUND PIPELINES CAUSED BY SHIELD CONSTRUCTION
-
摘要: 采用三维有限元方法,考虑土体、地下管线、盾壳以及衬砌的相互作用,用ANSYS程序软件模拟盾构推进对邻近地下管线位移的影响,探讨盾构刀盘推进力、盾构开挖面到地下管线不同距离、注浆程度等因素对地下管线位移的影响。Abstract: Considering the coupled action of soil, underground pipelines, shield shell and tunnel lining, with software of ANSYS, a three dimensional finite element method is used to analyze the displacements of underground pipelines caused by shield construction. Displacements of underground pipelines affected by the propelling force of shield, distance between working face of shield and pipelines as well as injected slurry etc are studied.
