摘要
采用三维有限元模型,从管线的位移场入手,对相邻深基坑开挖对周围管线影响的因素进行模拟和分析,重点从开挖步骤、管线埋深、管线距两相邻基坑的远近、管线材质、下卧层和管线与周围土体的模量比等六个方面进行分析,以管线的水平和竖向位移来检验六个因素对管线影响的大小并与工程实例进行对比分析。研究成果为设计、施工提供了一定的依据和参考。
Based on the analysis of the displacement field of buried pipeline between the two deep excavation, the effect factors on buried pipeline during excavation of two adjacent foundation are simulated and analyzed using 3D FEM. Several factors such as buried depth, distance from two adjacent excavations, pipeline materials, substratum, the ratio of the elastic modulus of pipeline to adjacent soil, etc. are analyzed primarily, and their influences on pipeline are checked by the horizontal and vertical displacement. Some valuable conclusions for construction practice are drawn.
