中文摘要：
采用几何非线性有限元方法研究海洋系？白缆索在重力、浮力和水流流体阻力作用下的静态平衡位形和张力分布。基于完全的Lagrangian格式，采用二节点等参索单元建立系泊缆索的静态平衡方程；采用增量迭代法求解得到的静平衡方程。数值算例证实此方法的有效性和准确性。计算了不同水流流体阻力作用下缆索的静平衡位形和张力分布，得到一些有意义的结论。
英文摘要：
A geometrically nonlinear finite element procedure is developed to predict the static position and tension of the cable under the action of self weights, buoyancy and current. Based on the Total Lagrangian Method, the isoparametric cable element with two nodes is used to estab- lish the static equilibrium equation of mooring lines. The equation is solved using the incremental iteration method. Numerical examples are presented to validate the present numerical method. The static equilibrium position and distribution of tension of the cable are computed under the action of different currents. Some significant conclusions are presented.
