摘　　要：船舶系缆力是码头结构设计和系船柱选型的重要条件,风、流、浪为船舶系缆力主要控制因素。针对国内外码头设计规范中船舶系缆力的计算方法差异,选取了码头结构设计常用的国内外规范(中国JTS规范、西班牙ROM规范、OCIMF指南、英国BS 6349规范)对船舶所受风荷载的计算公式进行对比分析,并结合工程实例对不同风向角下的风荷载进行了计算。结果表明:1)不同规范在船舶适应范围、风速选取、船舶受风面积、风压修正系数方面存在明显差异。2)ROM计算得出的30万吨级油船的风荷载最大,JTS计算结果最小。The mooring force of ships is an important condition for wharf structure design and mooring bollards selection.The wind,current and wave are the main controlling factors of ship mooring force.Regarding the differences in the calculation methods of ship mooring force in Chinese and foreign wharf structure design standard,the Chinese and foreign codes commonly used in the design of wharf structures(China JTS,Spanish ROM,OCIMF guideline,British BS 6349)are selected to compare and analyze the calculation formulas of wind loads on ships,and the wind loads under different wind direction angles are calculated combined with engineering examples.The result shows that:1)There are obvious differences among different standards in the adaptability range of ships,the selection of wind speed,the area of ships subjected to wind and the wind correction coefficient.2)The wind load of the 300,000 t tanker calculated by ROM is the largest,and the calculation result of JTS is the smallest.
