摘　　要：对于在沿海或海岛泻湖附近水域进行作业的浮体,因其较浅的工作水深使得海底地形变化对其系泊系统的影响不可忽略,因而在探究系泊系统特性时不能再将海底简化为平坦地形。为研究锚链在非平坦海底地形条件下的静态特性,基于集中质量法建立锚链模型,通过数值模拟探讨海底倾斜角度以及锚链布置方式对锚链顶端张力、张力角以及悬线长度的影响规律,以指导浅水水域浮体系泊系统的设计和安全性能评估。For floating structures deployed in waters near the coast or island lagoons,the shallow water depth makes the impact of seabed topography changes on the mooring system non-negligible,and the seabed can no longer be simplified as flat when exploring the characteristics of the mooring system.To study the static characteristics of the anchor chain under the condition of uneven seabed terrain,an anchor chain model was established based on the lumped mass method,and effects of the seabed inclination angle and the arrange⁃ment of the anchor chain on the tension and the tension angle at the top of the anchor chain,and the length of the catenary were discussed through numerical simulation,in an attempt to guide the design and safety perfor⁃mance evaluation of floating mooring system in shallow waters.
