归纳总结了管道穿越地震断层的分析方法及相关抗震设计规范，通过梳理海底管道与陆上管道在穿越地震断层分析上的差异，提出了海底管道穿越地震断层分析的推荐做法。依托工程案例，采用有限元方法，开展了地震断层作用下海底管道响应分析，并给出了设计优化建议。

This paper summarizes the analysis methods and relevant seismic design codes for pipeline crossing seismic fault. Based on the differences between seabed pipeline and onshore pipeline in analysis on crossing seismic fault, the recommended practices are proposed for analysis on seabed pipeline crossing seismic fault. For a given project case, the response of seabed pipeline subjected to seismic fault is analyzed by using the finite element method, and related design optimization measures are proposed.
