摘要
针对外海轻型码头结构的特点,通过能量法建立了系泊船舶在承受各种外部荷载时系缆力的数学模型,并编制了计算程序,给出了在2种外荷载工况下系缆力与缆绳和系船墩刚度比之间的变化关系.结果表明,缆绳和系船墩的刚度比对系缆力的影响很大,并且使系缆力发生重分配,系缆力变幅约为10%.因此,对于外海的轻型码头结构,在计算系缆力时,建议考虑缆绳与系船墩之间的刚度比对系缆力的影响.
Mooring force is studied according to the characteristics of open sea terminals structure.A mathematic model for calculating mooring forces is established based on energy method when the ship is subjected to external environmental loads.In addition,computer program is compiled.The relationships between mooring force and stiffness ratio of mooring line to moored platform are given for two external environmental conditions.Results show that stiffness ratio has a strong influence on mooring forces and then causes its redistribution.The change range of mooring force is in the average of around 10%.Therefore,the influence of stiffness ratio of mooring line to moored platform on mooring force should be considered when calculating mooring forces of open sea terminals structure.
