摘　　要：通过系列模型试验,对斜坡上尾部封闭式平板结构波浪上托力沿板宽分布进行了详细分析,提出板下最大冲击压强和最大总上托力并不一定同时出现,其分布形态可分为局部冲击型和均匀型。由于封闭空气层和底部斜坡影响,较大总上托力形成机理不尽一致,其均匀分布宽度也不相同,可分为气压型和反射型两类,由此提出分类标准,并分别得到压强分布的计算公式。This paper presents the result of an experimental study on the distribution of uplift pressure along a horizontal plate of a wharf on a slope exposed to a regular progressive wave. The results show that the distributing patterns corresponding to the maximum uplift pressure and the maximum uplift force respectively are different. Owing to the effects of air cushion closed under the plate and slope under the plate, there are two basic types of distributing patterns of uplift pressure corresponding to the maximum uplift force. A criterion, which may distinguish these two types of distributing patterns, is proposed. Finally, some empirical relationships are ob- tained for prediction of the two distributing patterns.
