海底管道稳定性分析

摘要

海底管道稳定性设计是海底管道整体设计的起始部分，也是海底管道设计的重要部分，该部分直接决定海管的选择形式。对海底管道稳定性分析的合理性直接影响着海管在整个运营周期内的安全和经济效益。结合现行主流设计规范，讨论海底管道稳定性分析涉及参数，研究海底管道分析设计方法，并为今后海底管道稳定性设计提供合理化建议。%　　On-bottom stability design of submarine pipeline is an important component of submarine pipeline integration design, whose analysis result determines the style of pipeline. The rationality of submarine pipeline on-bottom stability impacts on the stability and economic benefit of proposed submarine pipeline. Thanks to the primary submarine design code, the paper studies the parameters and methods used in on-bottom stability design of submarine pipeline. In the end, this paper provides recommendation for submarine pipeline on-bottom stability design, which is of value for further design of similar on-bottom stability study of submarine pipeline.
