摘要: 本文在分析现有海洋管道漂浮敷设充水下沉模型基础上,提出了一种同时考虑海底土壤与波浪流联合作用下充水下沉时管道的分析计算模型。借助于Laplace变换处理着底段管道,利用加权余量法和解非线性方程组的Brown算法,获得了该问题的近似解。文中算例说明了有关计算过程。

Abstract: This paper proposes a kind of analysis of sinking performance while filling-in water in float laying of offshore pipeline and a calculation model of the pipeline on which wave and current act simultaneously. An approximate solution is obtained with Laplace transformation to handle the pipe on sea bottom and by utilizing weighted residuals method and Brown method of solving non-linear equations. Finally, an example is given to show the calculation procedure.
