摘要

考虑了管道与土壤之间的相互作用及管道与流体之间的耦联作用 ,研究了埋地管线在横向传递的剪切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 :随土壤剪切模量增大 ,横向相对位移减小 ,弯曲应力减小 ;随管径增大 ,横向相对位移增大 ,弯曲应力增大 ;随流速增大 ,弯曲应力几乎不变 .
The seismic response analysis of buried pipelines due to the axial propagating S-wave is carried out considering the interaction between the pipe and the soil and considering the doubling of flowing fluid motion and the pipe motion. The motion equation is resolved in finite element method. The results of actual calculation show that with the increase of Gs, the relative displacement and the bending stress are reduced and the dynamic response variation can be very high; with the increase of D, the relative displacement and bending stress are increased; with the increase of V, the bending stress almost keeps consistent.
