长输管道竖向弹性敷设计算及有限元分析

本文提供了埋地钢质管道和管沟开挖的曲率半径、弧形管沟标高的计算方法,并利用ANsYs软件分析管道爬坡的垂直敷设高度与应力的关系,以及埋地管道弹性敷设在自重作用下的变形和自重与内压共同作用下的组合变形及其受力情况。分析结果为管道弹性敷设提供参考。

This paper provides curvature radius of buried pipelines and arc excavation, the calculation method of arc trench elevation, and use ANSYS software to analysis relation about pipeline climbing up running vertical height with the stress, deformation of elastic laying under gravity, and combination deformation and stress situation under combining gravity with inner pressure. The result provided the reference for piping flexible equiping
