摘　　要：本文以实际工程中点支撑托管架支撑下的海洋管道为分析对象，采用Ｂ样条函数分段拟合了从张紧器到海床间整段管道在铺设时的空间曲线，利用样条函数配点法求解管道的平衡微分方程，得到了管道在铺设过程中所必须的数据。本方法适用性好，理论简明，求解快，精度高。The submarine pipelines on the point supported stingers are analyzed in this paper. The authors simulate the 3 D curve of the submarine pipelines from tensioner to touch down point during installation by using B Spline, solve the difference equations of the curve by using the method of spline collocation, and obtain needed data during installation. The principle is clear, the results obtained by this method are equally accurate and less computational work is needed.
