不连续埋地管线在沉陷情况下的响应分析

Response analysis on discontinuous underground pipeline under subsidence condition

针对自应力水泥接口材料的不连续埋地管线在沉陷情况下的响应进行了分析,通过计算分析,得到自应力水泥接口材料管线的控制应力应变,通过与连续管线计算结果的对比可以发现,接口材料有利于降低管线的应力应变,但在接口处有明显的应力应变集中现象。

This article analyzes the response on discontinuous underground pipeline of self-stressing cement jointing materials under subsidence condition,obtains control stress-strain of self-stressing cement jointing material by calculation analysis.Through comparing to continuous pipeline calculation results,it finds that jointing materials are useful to reduce pipeline stress-strain,but it has obvious stress-strain concentration phenomenon at jointing part.
