摘　　要：为保证海洋管道在收弃管作业过程中不发生屈服 ,利用样条函数配点法分析了管道的变形 ,利用线性积分法分析了缆索的收放和受力 ,以图表的形式给出了管道和缆索的受力和变形、铺管船的运动以及 A/To enable A/R operation to be carried out without overstressing the pipeline, the deformation of the pipeline is solved by using the spline collocation method while the cable attached to the pipeline is analyzed by employing a line integration technique.The graphical approach is presented for showing the relationship among the deformation and forces of the pipeline and cable,the motion of the lay barge and the tension of the A/R winch.
