摘要 本文将航道和波浪作用的全场波能分布极化为回折型反射、绕射和直射 3区 ;利用平底单堤绕射能的经典结果 ,获得了堤前最大的比波高值不随入射角而变的特点 ;考虑缓滩坡度的折射影响 ,和迎浪坡面焦散线的虚拟特性 ,确定航道附近最大波能限值控制为 :计算最大波能位置对应的缓滩纯折射波能的 2 .34倍。 The wave energy distribution in a full field in the vicinity of navigation channel under the action of waves is simplified into three regions, namely the reflection with refracted waves of returning type, diffraction and incidence. By using the classic results of the diffracted wave energy for a flat bottom single breakwater, it is obtained that the maximum values of specific wave height in front of the breakwater do not change with the incident wave angles. Considering the influence of the slope of a gentle beach upon the refraction and the virtual characteristics of the caustic lines of the slope facing incident waves, the controlled ultimate values of the maximum wave energy in the vicinity of navigation channel are determined to be 2.34 times the pure energy of the refracted waves on the gentle beach corresponding to the location for maximum wave energy calculation .This controlled estimation is supported by mathematical model calculations.
