比较全面地分析并概述了海底管线抗震设计所面临的问题；结合工程应用，给出了解决这些问题的基本思路和建议，希望能够对海底管线抗震设计方法研究和抗震规范的制定提供一定的帮助。

The paper comprehensively analyzes and summarizes main problems that exist in seismic stress calculation of offshore pipelines. In combination with demands of engineering design, some thoughts and advice are given to deal with the problems, which are expected to benefit researches on anti-seismic design method, in addition to establishment of anti-seismic criterion of offshore pipelines.
