为了研究组合式趸船浮式防波堤的运动响应与锚链受力，本文基于Ansys AQWA软件进行数值模拟，系统探究了T型块几何参数（宽度、高度）、锚泊方式（平行锚泊、交叉锚泊）及波浪要素（波高、周期）对防波堤水动力特性的影响。研究结果表明，系泊状态下，交叉锚泊有效降低横摇与横荡幅值，但垂荡响应受波浪周期影响显著。平行锚泊（张紧）的峰值张力与平均张力最高，但稳定性最优；交叉锚泊在降低峰值张力的同时提升了多向约束能力一定程度上增加浮体的稳定性；锚链拖地虽张力最低，但稳定性不足，易引发浮体的大幅运动。锚链受力分析表明，迎浪侧峰值张力随波高与周期呈非线性增长，深吃水工况（d=2.0 m）下易因共振导致张力激增。
To investigate the motion response and mooring chain forces of a composite pontoon floating breakwater, numerical simulations were conducted using Ansys AQWA software. we systematically investigated the impacts of T-block geometric parameters (width, height), mooring configurations (parallel mooring, cross mooring), and wave characteristics (wave height, period) on hydrodynamic performance. The results demonstrate that under moored conditions, cross-anchoring effectively reduces roll and sway amplitudes, while the heave response is significantly influenced by wave period. Parallel-anchoring (tensioned) exhibits the highest peak tension and mean tension, yet provides optimal stability. Cross-anchoring reduces peak tension while enhancing multi-directional restraint capability, thereby increasing floating body stability to some extent. Although ground-touching anchor chains yield the lowest tension, their insufficient stability may induce large-amplitude motions of the floating body. Mooring force analysis indicated nonlinear growth of peak tension on weatherside chains with increasing wave height and period, with deep-draft conditions (d=2.0 m) showing tension surges due to resonance.
