防波堤及护岸越浪研究综述

近年来防波堤越浪方面的相关研究,分别在越浪影响因素、越浪量计算公式推导论证、越浪数值模拟与越浪量标准4个方面进行归纳总结.已有成果表明:1)越浪影响因素的研究多是集中于常规因素,包括波高周期,堤顶高程,坡肩宽度,护面块体,而对水流、风速、波浪谱以及水的性质等其他因素研究相对较少;2)越浪量计算公式研究中主要集中在影响越...

A review of research on overtopping of breakwater and revetment

Through collecting and sorting out the relevant researches on breakwater overtopping in recent years,this paper summarizes the influence of overtopping factors,the deduction and demonstration of overtopping calculation formula,overtopping numerical simulation and overtopping standard.The existing results show that:most of the factors of overtopping are focused on the study of conventional factors,including wave height period,dike top elevation,slope shoulder width and armor block,while the study of other factors such as flow,wind speed,wave spectrum and water properties is relatively less;the study of overtopping calculation formula mainly focuses on three aspects:the factors affecting overtopping,the comparison and selection of overtopping formula,and the derivation of formula.In the aspect of numerical simulation,RANS equation and RNG model are mostly used Based on k-εturbulence model and VOF method,fluent and other mature softwares are used to simulate the overtopping process or predict the overtopping amount.Machine learning algorithms such as neural network are more and more used in the numerical simulation of overtopping amount.With the deepening of the above research,the overtopping standard has gradually improved,and the applicability has been strengthened to a certain extent.
