复杂水动力条件下大型开敞式码头轴线的确定

对20万吨级以上、动力要素十分复杂的海域，码头轴线的确定需要考虑船舶对码头结构的作用、码头可作业天数及作业效率、航道引水靠泊作业等多种要素。以大连矿石专用码头工程为背景，通过物理模型试验，系统测量了波浪、潮流、风等动力要素耦合作用下的船舶对码头结构、系缆设施及护舷的作用；给出了波浪和潮流不同夹角时船舶系靠泊状态下的运动量及缆绳拉力的变化规律。通过对水文资料及水动力试验结果的综合分析，考虑航道引水靠泊作业之要素，优化确定出码头轴线方位，该结果可为同类码头工程设计提供参考。

Determination of Axial Line of Large Open Wharf Under Complicated Hydraulic Conditions

In sea waters of complicated dynamic factors,determination of the axial line of wharf over 200000t shall consider multiple factors including function of vessels on the wharf,wharf workable days and working efficiency,as well as berthing operation.Basing on Dalian Specialized Ore Terminal engineering,through physical model experiment,the function of vessel under the action of wave,tide and wind to wharf structures is tested,variation law of vessel's motion when berthing and mooring at different angles of wave and tide and cable's tensile force are given.Basing on the comprehensive analysis of the hydrological data and hydro-dynamic experimental results,and considering the factors concerning berthing operation,the direction of wharf's axial line is determined,serving as a reference for similar wharf engineering.
