摘要
防波堤是码头掩护的重要屏障,其较高的投资往往成为工程可研阶段方案决策的关键因素。针对粤东某码头的防波堤优化,在收集附近外海波浪实测资料的基础上,结合波浪数值模拟成果,建立外海测波点与码头前沿的波要素转换关系,得到不同方案所对应的可作业时间,为防波堤建设方案的决策提供可靠的数据支撑。结果表明,同方向的外海入射波浪具有基本一致的波浪转换系数,利用该特性能够简化可作业时间的统计工作,提高方案比选效率。
The breakwater is an important barrier to a wharf,and its high investment often becomes the key factor of scheme decision-making in the feasibility study stage of a project.For optimal design of the breakwater for a wharf project in eastern Guangdong,we collect the measured offshore wave data near the project.On this basis,we establish the transformation relation of wave elements between offshore wave measuring area and wharf front area considering the numerical simulations of waves.In this way,we can obtain the operational time corresponding to different schemes,which can provide reliable data for decision-making of the breakwater construction scheme.The results reveal that offshore waves incident in the same direction have the same transformation coefficient.This feature can be used to simplify the statistical work of operational time and improve the efficiency of scheme selection.
