给出悬链线和缓波形理论公式的基础上，对某一深海脐带缆进行悬链线布局和缓波形布局两种不同布局形式的选型设计研究，计算得到脐带缆在两种布局下的静态和动态响应，及其有效张力和弯曲曲率的分布特性。结果显示有效张力的最大值都发生在悬链线布局和缓波形布局的顶部悬挂点，而弯曲曲率的最大值发生在悬链线布局的触地点和缓波形布局的上升段末端；缓波形布局在减小有效张力的同时还减小顶部浮体和波浪运动对脐带缆的动态干扰。%A free hanging catenary shape and a lazy-wave shape were designed for some deepwater umbilical based on the theoretical equations of the two kinds of shapes.The static and dynamic responses of the umbilical under both shapes were calculated,and the distribution characteristics of effective tension and bending curvature were analysed.The results show that the maximum effective tensions all happen at the top hanging points of both shapes,but the maximum curvatures happen at the touchdown point (TDP)of the free hanging catenary shape and the lift section's endpoint of the lazy-wave shape.In addition,the lazy-wave shape can reduce the effective tension and the dynamic interference to umbilical caused by the motion of top float and wave.
