Other Abstract基于MIDAS结构分析软件,采用大变形壳有限元方法分析了大口径油气管道在断层位错作用下的应变响应。考虑管道与土体的非线性和管土耦合作用,系统分析了不同断层类型下不同交叉角度对管道应变的影响,得到了断层与管道的交角对管道应变响应的影响规律和变化曲线,并在此基础上,总结得到了不同覆盖土层厚度下管道穿越断层的最佳交叉角度。 
; Based on structural analysis software MIDAS, the strain response of large diameter oil and gas pipeline under dislocation of faults was analyzed by large deformation shell finite element method. Considering pipeline-soil coupling and material nonlinearity of both pipeline and soil, the influence of different crossing angles on the pipeline response in different types of earthquake fault was analyzed systematically, the influence law and variation curve of strain response of pipelines for different crossing angles were acquired. Based on the results, the optimal crossing angle of oil - gas pipeline passing through earthquake fault at different cover thickness is obtained.
