在海啸或风暴潮事件期间，沿海基础设施和港口受到一系列不同的物理危害，可能造成重大破坏和生命损失。其中，淹没事件期间的碎片撞击载荷是混乱、复杂的，迄今为止人们对它的了解很少，特别是在考虑单个碎片堆积成一个大碎片场时。这项工作提供了一个全面的实验研究的影响和随后的筑坝混乱的碎片领域，包括400多个单独的试验的结果;本文件的范围描述了实验设计和初步分析波驱动碎片诱导加载选择配置。这些数据既包括撞击现象，也包括随后碎片堆积形成的堤坝，并发现碎片场密度增加与撞击力增大之间存在着很强的相关性。高频冲击力和低频筑坝信号通过快速傅立叶变换方法被考虑。介绍了大碎片场对波浪引起的碎片的作用力的总体趋势。
During a tsunami or storm surge event, coastal infrastructure and ports are subject to a series of disparate physical hazards that can cause significant damage and loss of life. Among these, debris impact loading during inundation events is chaotic, complex, and thus far minimally understood, especially when considering the accumulation of individual debris into a large debris field. This work provides the results of a comprehensive experimental study of the impact and subsequent damming of chaotic debris fields, including more than 400 individual trials; this scope of this paper describes the experimental design and initial analysis of wave-driven debris-induced loading for select configurations. These data include both the impact phenomena and subsequent damming by debris accumulation and find strong correlation between increasing debris field density and high impact forces. High frequency impact forces and low frequency damming signals are considered via fast Fourier transform methods. Overall trends in wave-induced debris forcing from large debris fields are presented.
