摘　　要：海底管道的建设往往需要考虑地震和断层的影响,但是目前主要还是参考陆地管道抗震规范,其计算结果与海底管道工程实际存在较大的差距。为提高海底管道应力(应变)分析精度,基于管道-土体之间的相互作用建立了海底管道抗震分析方法,采用C语言和MATLAB平台开发了海底管道抗震分析软件,既可以进行海底管道的地震反应分析、穿越断层分析和弹性时程分析,又可以绘制海底管道的应力-应变曲线、地震波时程曲线和管道时程分析曲线,具有通用性强、交互方便、快速易用等特点,为海底管道的设计、施工提供了技术支持。The construction of submarine pipeline can be affected inevitably by earthquake or fault movement. However, land pipeline codes are still used for seismic design of submarine pipeline and the results are obviously different from those of engineering practice. Therefore, in order to improve the analytical precision of submarine pipeline stress or strain, a seismic analysis method was established on the basis of pipe-soil interaction and the seismic analysis software was developed by C language and MATLAB software, by which seismic response analysis, fault-crossing analysis and elastic time-history analysis can be conducted as well as plots of pipe stress-strain curve, seismic time-history curve and pipe time-history curve. Due to its general use and friendly interface, the software can be easily used by engineers and technicians in the design and construction of submarine pipelines.
