摘要
以带有刚性基础的沟埋式管道为例 ,介绍了利用ANSYS软件进行管道结构有限元分析的基本过程 ,包括模型的建立、边界条件与荷载的施加、问题的求解和结果的分析。本文分析了管壁环向应力分布规律 ,指出管顶、管底和管侧为管壁的三个控制性截面 ,并与结构力学方法、边界单元法的计算结果进行了比较 ;同时 ,对管周回填土的沉陷进行了分析 ,并与马斯顿的“等沉陷层”
The basic structural analysis of filled conduit was done with the ANSYS program. The basic process includes building of model, applying of boundary condition and loads, solving of model and analysis of result. The distributed law of annular stress of conduit was done. This paper pointed that the sections of conduit top, conduit bottom and conduit side were the key sections. The stress of conduit of ANSYS analysis method was compared with The Structural Method and BEM Method. At the same time, the deformation of backfilled earth around conduit was done and compared to the theory of Anson Marston.
