摘　　要：基于波浪作用下船舶系缆力的试验资料,分析了船舶特性、波浪参数对系泊船舶波浪力的影响规律,提出了作用于船舶上的波浪总力计算公式.参照《港口工程荷载规范》(JTJ215—98)由风和水流产生的船舶系缆力的计算方法,提出了由波浪产生的船舶系缆力的计算方法.算例表明,船舶系缆力的计算值与试验结果吻合较好.本方法可为工程设计中船舶系缆力的确定提供参考,填补了《港口工程荷载规范》(JTJ215—98)缺少波浪作用下船舶系缆力计算的空白.According to test result of physical model on mooring force,the influence of ship feature and wave pa-rameters on wave loading of mooring ship was analyzed and a new calculating method of total force induced by wave on the ship was proposed.Then a calculation method of mooring force induced by waves was put forward referring to the method of mooring force induced by wind and currents adopted by Load Code for Harbor Engineering（JTJ215— 98）.The examples indicated that the calculated results accorded with the test results very well.It was concluded that the new method could be a good reference for mooring force of ship design and fill the blank of Load Code for Harbor Engineering（JTJ215—98）,which did not consider the calculation of mooring force induced by waves.
