摘要
考虑了管道与土壤之间及管道与液体之间的相互作用 ,研究了埋地管线在轴向传递的压缩波作用下的动力响应 ,利用有限元方法对运动方程求解 .对实际算例运算结果表明 :随土壤剪切模量的增大 ,轴向相对位移减小 ,轴向应力降低不明显 ;随管径增大 ,轴向相对位移增大 ,轴向应力降低不明显 ;随流速增大 ,轴向相对位移增大 ,轴向应力不变 .
The seismic response analysis of buried pipelines due to the axial propagating P\|wave is carried out considering the interaction between the pipe and the soil and the interaction between the fluid and the pipe at the same time. The motion equation is resolved in finite element method. Actual calculations show that with the increase of Gs, the relative axial displacement and the axial stress are reduced; with the increase of D, the relative axial displacement is increased and the axial stress is not reduced obviously; with the increase of V, the relative axial displacement is increased and the axial stress keeps consistent.
