【摘要】：在理论分析的基础上通过物理模型实验研究了海啸波与近岸植物的相互作用。实验中借助孤立波模拟海啸波,并采用综合考虑根、茎、叶的植物模型,分析了近岸植物根、茎、叶及分布密度对海啸波消减特性的影响。结果表明,根、茎、叶均在不同程度上对近岸植物消波特性产生影响,本次实验条件下得到了孤立波透射系数与表征水动力因素的相对波高及表征植物因素的相对树根高度、相对树干高度、相对树冠高度、相对植物带宽度、分布密度之间的关系式,揭示了近岸植物消波特性与水动力因素和植物因素的内在联系,为减小海啸灾害提供一定的理论指导。
[Abstract]:On the basis of theoretical analysis, the interaction between tsunami wave and inshore plant was studied by physical model experiment. In the experiment, the tsunami wave was simulated by using solitary wave, and the plant model considering root, stem and leaf was used to analyze the root and stem of inshore plant. Effects of leaf and distribution density on the characteristics of tsunami wave subtraction. The results showed that roots, stems and leaves all affected the wave attenuation characteristics of coastal plants in varying degrees. The relative wave height, relative tree root height, relative tree stem height, relative crown height, relative width of plant belt, and relative wave height of hydrodynamic factors were obtained under the experimental conditions, and the relative wave height of relative wave transmission coefficient and the relative height of tree root, relative stem height, relative crown height and relative width of plant belt were obtained. The relationship between the distribution density reveals the inherent relationship between the wave dissipation characteristics of coastal plants and hydrodynamic factors and plant factors and provides some theoretical guidance for reducing the tsunami disaster.
