本文采用了一种新的边界条件对海洋平台张力腿的横向运动进行研究，并以通用的边界条件作比较分析两种边界条件下张力腿的动态响应。同时还研究了多项伽辽金法的精确度问题。所得结论对ＴＬＰ的设计具有重要的参考价值。
In this paper, a new boundary condition is used to study the lateral movement of the tension leg of the offshore platform. The dynamic response of the tension leg under the two boundary conditions is compared with the general boundary conditions. At the same time, the accuracy of many Galerkin methods has also been studied. The conclusions obtained have important reference value for the design of TLP.
