【摘要】：在海岸帶種植紅樹林等水生植物可以有效的減小波浪對岸灘的破壞,系統(tǒng)全面地研究植物對波浪傳播變形的影響是非常必要的�；诓ɡ怂蹖嶒�,探討了規(guī)則波通過非淹沒剛性植物波高的沿程變化,分析了水深、入射波高、植物模型密度及分布方式對反射系數(shù)、透射系數(shù)與波浪衰減系數(shù)的影響,同時與孤立波實驗數(shù)據(jù)進行對比。實驗結(jié)果表明,隨著水深的增加,規(guī)則波的透射系數(shù)增加、反射系數(shù)和波能衰減系數(shù)減小;隨著入射波高的增加,規(guī)則波的透射系數(shù)減小,反射系數(shù)和波能衰減系數(shù)增加。在分布方式相同的情況下,植物模型分布密度增加,規(guī)則波的反射系數(shù)和波能衰減系數(shù)增加,透射系數(shù)減小。在規(guī)則波入射方向上模型布置越緊密,規(guī)則波反射系數(shù)和波能衰減系數(shù)越大,透射系數(shù)越小。分析討論了植物模型對規(guī)則波和孤立波的影響,在入射波要素相同的情況下,孤立波和規(guī)則波的能量衰減在50%左右,說明植物模型具有良好的消波作用。
[Abstract]:Planting mangroves and other aquatic plants in the coastal zone can effectively reduce the wave damage to the shoreline. It is necessary to systematically and comprehensively study the effects of plants on the wave propagation and deformation. The variation of regular wave through the wave height of non-submerged rigid plant is discussed. The effects of water depth, incident wave height, plant model density and distribution mode on reflection coefficient, transmission coefficient and wave attenuation coefficient are analyzed. The experimental results show that with the increase of water depth, the transmission coefficient of regular wave increases, the reflection coefficient and attenuation coefficient of wave energy decrease, and the transmission coefficient of regular wave decreases with the increase of incident wave height. Under the same distribution pattern, the distribution density of plant model increases, and the reflection coefficient and attenuation coefficient of regular wave increase. The closer the model is arranged in the incident direction of regular wave, the larger the reflection coefficient and attenuation coefficient of regular wave are, and the smaller the transmission coefficient is. The influence of plant model on regular wave and solitary wave is analyzed and discussed. The energy attenuation of solitary wave and regular wave is about 50% when the incident wave elements are the same, indicating that the plant model has good wave dissipation effect.
