摘要
采用物理模型试验探求不规则波作用下的直立建筑物迎浪面的波谷压力概率分布规律。试验表明,直墙前立波和破碎波两种波浪形态作用下,均可采用韦伯分布来描述波压力概率分布,得出了韦伯分布的形状参数与相对基床高度、基床前肩宽和相对波高有关,并拟合给出经验公式。经可靠性检验表明拟合是合理可靠的。
This paper presents result on the random wave trough forces on a vertical-wall structure. The waveused in the tests is directional and irregular wave. The experiments are carried out with different foundation bedheight and width, and different relative wave height. Based on the probabilistic analysis of model test data of irregu-lar standing and breaking wave trough loads on vertical walls, it is indicated that the probabilistic distribution canbe expressed by Weibull formulation, in which the parameter β is well related to wave parameters as well as the pa-rameter of rubble mound foundation, and the parameter η can be obtained by the theoretical relation between β andη. The calculated results agree well with the test data.
