深基坑开挖诱发管线变形规律的数值模拟研究
Numerical simulation of deformation law of pipelines induced by deep excavation
摘要
Abstract
The numerical simulation of underground pipeline deformation induced by deep excavation was car-ried out by using Midas software,and the influence of pipeline buried depth,distance between pipeline and foundation pit,number of support and type of pipeline on the deformation of pipeline was analyzed emphatical-ly.The results show that:(1)There is a certain correlation between pipeline deformation and buried depth, the horizontal displacement and vertical displacement of pipelines are gradually reduced with the increase of buried depth;(2)The closer the pipeline is to the foundation pit,the greater the deformation;(3)The de-formation of pipeline is related to its elastic modulus,the smaller the modulus is,the greater the deformation is,and(4)The displacement of the pipeline decreases.关键词
