摘要

在穿越断层埋地管线原位足尺试验的基础上

借助于有限元分析软件ABAQUS建立三维有限元模型

并将有限元分析结果和试验分析结果进行对比以确定建立模型的正确性。利用有限元模型对试验工况进行补充分析

通过对逆断层作用下管道和周围土体的反应模拟结果确定地震中管道变形对周围土体的影响区域。分析对影响区域可能造成影响的各个参数

从管径、管道埋深、断层面倾角、位错量、土体刚度5个方面研究了其变化对影响区域可能造成的影响。

Abstract

Based on results of the in-situ and full scale experiment

a three-dimensional finite element model is established to evaluate the range of computational region in the pipe-soil interaction system. The results of finite element analysis are compared with the experimental results in order to confirm the validity of the model

and responses of pipeline and surrounded soil are analyzed. Finally

some influence parameters such as diameter of pipe

bury depth

the angle of fault plane

fault displacement

shear wave velocity of soil

are investigated.
