Abstract: Theories and methods for marine pipeline stability design was discussed and some improvement was made.Based on the study of the principles of stability design,a procedure was put forward for marine pipeline stability designing,which combines some current pipeline design regulations by optimizing.Some factors influencing the stability of the pipeline which have not been included by the conventional design codes were considered.

Key words: marine pipeline, stability design, wave, earthqtuake, specifications

摘要： 对海底管道稳定性设计的理论和方法进行了研究和探讨,明确了海底管道稳定性设计应该和必须考虑的问题,以及考虑这些问题的依据和机理.对国内外某些设计理论和设计方法进行了分析、综合和改进,并增加了目前国内设计中应该考虑而尚未考虑的设计内容.在此基础上,建立了一个海底管道的稳定性设计系统,通过系统的推理、判断功能,使设计合理地考虑尽可能多的因素,从而实现设计方案的优化.
