中文摘要：
通过建立波浪作用下锚碇沉管管段运动的时域数值计算模型，对锚碇沉管的运动响应及锚碇缆受力特性进行了研究。应用集中质量法求解锚碇缆力，应用四阶Runge—Kutta法求解管段时域运动方程，计算了在不同沉深、不同周期、不同波高和不同波向条件下沉管管段的运动幅值和锚碇缆力。数值计算的结果表明：锚碇沉管的锚碇缆对沉管管段的运动起到一定的约束作用，在沉放深度较浅、波浪周期较大时，锚碇缆对沉管管段运动幅度的制约更为明显。通过五种布缆方式的计算与分析，探讨了布缆方式对沉管管段运动响应及锚碇缆受力的影响，并给出了较为合理的布缆方案。
英文摘要：
The motion response and mooring line tensions of the tunnel element with mooring lines are studied by the time-domain numerical model. The time-domain motion equations of immerged tunnel element are solved by the fourth order Runger-Kutta method and the mooring line tensions are solved on the basis of the lumped-mass method. The motion responses and mooring line tensions of the immerged tunnel element are computed under different wave directions, wave heights, wave periods and immerged depths. The numerical results indicate that the mooring lines have certain effects to reduce the motions of the immerged tunnel, especially under the condition of lower immerged depth and a long period wave. The effects of mooring line arrangements on the motions are discussed and the better mooring line arrangements are given in the paper.
