【摘要】 采用圆柱壳单元模型模拟埋地管道,用非线性土弹簧模拟管—土之间的相互作用,通过有限元软件ANSYS分析了地震活动断层作用下埋地管道的非线性大变形反应。研究了对管道震害造成影响的各项工程参数,包括管道跨越角度、管道埋深、管径、管道径厚比、场地土类型、管材等,可为埋地管道抗震设计提供重要依据。更多还原

【Abstract】 An analysis model is constructed by using cylindrical shell element to simulate buried pipeline and nonlinear spring to simulate the interaction of pipe soil system.The large deformation nonlinearized in a buried pipeline under fault movement is analyzed using finite element software ANSYS.Some influential factors on seismic responses of buried pipeline are studied,such as angles between pipeline and fault,buried depth of pipeline,diameter of pipeline,ratio of diameter to thickness of pipeline,style of soil and pipe materials.which provides an important base in buried pipeline’s aseismic research and design.更多还原
