    破碎波对防波堤冲击作用研究进展

    Review of research of breaking wave impact on breakwater

    • 摘要: 破碎波对防波堤的冲击作用是导致防波堤滑移失效的主要原因。但由于冲击过程具有湍流特征,海岸工程领域对冲击作用的认知还不够深入,针对冲击作用的防波堤设计流程也有待完善。鉴于此,本文对破碎波对防波堤的冲击作用的研究进展进行了梳理和总结。首先,总览了过去80余年的研究历程,并将其分为起步阶段、爆发阶段与攻坚阶段,归纳了各阶段的特点与成果。其次,探讨了针对冲击过程的四部分研究,即冲击类型划分、冲击压强峰值、压强振荡和尺度效应。最后,回顾了冲击波浪力计算方法与冲击波浪力作用下防波堤稳定性验算两方面针对冲击波浪力的研究。研究表明:①空气的存在是冲击作用难以解析的主要原因,量化由空气引起的冲击过程不确定性是本问题未来重要的研究方向;②虽然第二代冲击波浪力计算方法均偏于保守,但仍在适用性和结果一致性方面存在问题,建立合理、统一的冲击波浪力计算方法并在此基础上发展动力条件下的防波堤稳定性验算方法是开展冲击作用研究的长期目标。

       

      Abstract: The impact of breaking waves is regarded as the main reason for the sliding failure of breakwaters. However, the impact process is not deeply understood due to its turbulence feature, and the breakwater designing procedure under the impact condition requires to improved likewise. Therefore, the paper reviews the research of breaking wave impact on breakwaters. First, an overview of the research in the past 80 years is presented. The research has been divided into three stages: starting, explosive, and conquering, and the feature and achievement of each stage are summarized. Second, attentions are taken to four aspects of the impact process research, namely, impact classification, peak impulsive pressure, pressure oscillation, and scale effect. Finally, the two aspects of the research on impulsive wave force, that is, impulsive wave force calculation and dynamic response of breakwaters against breaking wave impact, are reviewed. The result indicates that the presence of air is the crux of the research and quantizing the uncertainty introduced by air is the important research direction of this issue. Although all the second-generation impulsive wave force calculation methods yield conservative results, the problems of applicability and result consistency still exist, which means that establishing reasonable and uniform impulsive wave force calculation methods, as well as developing breakwater stability analysis methods under dynamic conditions is the long-term goal of this issue.
