| 摘 要： | 采用Abaqus有限元分析软件，建立三维模型，模拟隧道开挖对地下管线的影响，充分考虑了不同的埋深、材质、下卧层刚度等条件。结果表明，管线周围土的性状，与双线隧道的相对位置以及管线自身刚度、管径等不同，将对其变形和内力产生较大影响，从而得出一些规律，为今后类似工程施工提供依据。

| Abstract: | Based on ABAQUS program, 3-D finite element analysis model is established to simulate the effects of tunnel excavation on underground pipeline, in which different embedments, material properties and,, stiffnesses of subjacent bed are considered. The . results show that the different soil properties and stiffnesses, caliber of pipeline have great influences on its deformation and internal force. Some conclusions are drawn to provide corresponding guidance for subsequent projects. |
