| 摘 要： | 本文采用圆柱壳单元模拟地下管道,用有限元模拟手段建立了管道-土相互作用分析模型,采用非线性接触问题分析方法分析了管道因断层运动而产生的反应,通过大量数值计算,对影响管道地震反应的各种因素进行了研究,如断层位错量、管道跨越角、断层运动方式、管道埋设深度、管道初始轴向力、断层裂缝宽度、管道径厚比等,得到了一些规律性的结论。

| Abstract: | The analysis model of pipe-soil system was constructed using cylindrical shell element to simulate the buried pipeline on the basis of the finite element simulation method.The seismic responses of pipeline are analyzed by the nonlinear contact problem method.Some influential factors on the responses of buried pipeline were studied by numerical calculation,such as the displacements of active fault,the angles between pipeline and fault,the forms of fault movement,the burying depth of pipeline,the initial axial force on pipeline,the width of the lap,the ratio of diameter to thickness of pipeline,and some conclusions are drawn. |
