三维土-管道相互作用及地震反应分析
|
摘要
在地震作用下,由于土与管道相互作用,常会导致管道严重破坏。建立了管线地震反应的三维计算模型,采用静态Mindin解和动平面解相结合的方法,考虑半无限三维空间中各维间的耦合作用,求解了三维土-管相互作用,进行了三维地震反应分析。利用本章建立的三维模型可进行管网的地震分析.
The interaction between soil and pipeline usually induces destruction of the pipeline under earthquake action.This paper establishes a 3D seismic response calculation model of pipeline.Based on combination of static Mindin solution with dynamic plane solution and coupling between dimensions in infinite semispace,the 3D soil-pipeline interaction problem was solved,the 3D seismic response analysis was carried out.By use of the 3D model presented in this paper,it is possible to conduct seismic response analysis of pipeline network.
