摘　　要：运用无网格再生核质点法(RKPM)对地下长输管道的纵向地震响应进行分析.与现有的级数法及有限元法相比,RKPM法无需网格,其变时频特性和多分辨率分析的优点,使之成为求解管道地震响应和其它结构动力学问题的有效方法.A mesh free approach,Reproducing Kernel Particle Method(RKPM),is applied for the first time to analyze longitudinal seismic wave propagation in buried pipelines.Compared with other existing analysis methods,such as series analytical method or standard mesh-based Finite Element Methods,the inherit mesh free and flexible time-frequency characteristics make RKPM a novel alternative for seismic analysis of pipelines and other structural dynamics problems.
