应用ANSYS软件分析地下埋管工程

The Application of ANSYS to Filled Conduit Analysis

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。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3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"理论作了比较。

Filled conduit is adopted as an example to analyze the finite elements of its structure by ANSYS program. The distributed law of the annular stress of conduit is analyzed and it is pointed out that the conduit top, bottom and side are the key conduit sections. Meanwhile, the results of ANSYS analysis are compared with those of structural mechanics and BEM method. At the same time, the deformation of backfilled earth around conduit is analyzed and compared with Anson Marston's theory.
