摘　　要：港口是以性能需求为最终目标导向的特殊工程主体,保障港口安全与性能需求的防波堤在港口平面布置中占有重要地位。基于巴基斯坦某电厂港口项目,在中长周期涌浪条件下,通过电厂燃煤补给及消耗模型确定港区性能需求,利用数值模拟分析,建立波高、周期与船舶运动量的关系,并将其作为岛式防波堤防护效果的重要标准之一,从而合理确定岛式防波堤平面布置方案。结果表明,方案2为最终设计方案,可满足年作业时间的要求。The port is a special engineering subject with performance requirements as the ultimate goal.The breakwater guarantees the safety and performance requirements of the port,and it plays an important role in the general layout of the port.Based on the port project of a power plant in Pakistan,we determine the performance requirements of the port area by the coal-fired recharge and consumption model of the power plant under the conditions of the mid-long period wave surge,use the numerical simulation analysis to establish the relationship among wave height,period and ship motion,apply it as an important standard for the protection effect of the island-type breakwater,and determine the general layout scheme of island-type breakwater reasonably.The results show that the second scheme is the final design scheme,which can meet the requirements of annual operation time.
