摘要
本文提出了同时考虑海底基础及波浪作用之海洋管道'J'型铺设过程的分析模型,导出了着底管道与悬跨管段的控制微分方程。借助于加权残数法,采用双重迭代枝术获得了问题的近似解。文末算例分析了各主要参数间的变化关系。
Considering both seabed foundation and wave,the nuthor proposed an analysis model of 'J' type for offshore pipeline-laying. The article also obtains the control differential equation for the pipeline on the seabed and suspension sections. By utilizing weighted - residual method and dual iteration technique,an approximate solution is obtained, too. In the end, the article provides calculation examples for analyzing the changeable relationship among the major parameters.
