| 摘 要： | 针对一种新型的混凝土护面砌块，分别采用规则波和不规则波进行波浪水槽试验．在分析研究波浪对砌块护坡作用机理的基础上，通过护面砌块稳定性系列试验得出了规则波和不规则波作用下的砌块厚度计算公式．试验结果表明，块体厚度和波高成正比，并和破波参数、块体水下相对密度等因素有关．通过与混凝土砌块和混凝土板的几种常用厚度计算公式的比较，验证了该计算公式的合理性．

| Abstract: | Model tests were carried out on the stability of a new type concrete block revetment under regular and irregular waves in a wave flume. Based on an analysis of the mechanism of wave action on the revetment, formulae for block thickness under the actions of regular and irregular waves were obtained through a series of stability tests. The results show that the block thickness is in direct proportional to wave height and also related to the break parameter and block density in water. Compared with several thickness formulae for concrete blocks and slabs conventionally used, the present formulae give a reasonable result. |
