本文应用边界单元法求解半无限空间中管线与土间的动力相互作用系数,进而求解管线在地震波作用下的反应。文中还对有关影响管线反应的参数进行了分析。可以看出管线的动力特性并不十分显著。另外管线的埋深对管与土间的相互作用,在埋深较浅时,有较大的影响。这种方法也适用于其它类似的工程问题。
In this paper, the boundary element method is used to solve the dynamic interaction coefficient between pipeline and soil in semi-infinite space, and then to solve the response of the pipeline under the action of seismic waves. The text also analyzes the parameters affecting the pipeline reaction. It can be seen that the dynamic characteristics of the pipeline are not very significant. In addition, the burial depth of the pipeline has a great influence on the interaction between the pipe and the soil when the depth of burial is shallow. This method is also suitable for other similar engineering problems.
