摘　　要：采用Ｂ样条函数分段拟合了海洋管道在铺设时的变形曲线，利用加权残数的配点法求解管道的平衡微分方程，得到管道的变形情况．本方法适用范围广，理论简明，求解快，精度高．? 2D curve of the pipelines is imitated by using B spline functions. The differential equations are solved by the method of collocation, and the deformed data are obtained. The principle is clear. The results are equally accurate, and less computational work is done.
