Stability of armour units on rubble-mound breakwater under multi-directional waves

摘要: 试验研究了扭工字块体、钩连块体、四脚空心方块和块石等四种护面块体在五种波向角(0°,15°,30°,45°和60°)的斜向波和多向不规则波作用下的稳定性,给出了四种护面块体稳定重量的实用计算方法.Abstract: An extensive 3-dimensional model test program has been performed to study the effects of wave obliquity and multi-directionality on the stability of armourunits on rubble-mound breakwater.Four types of armour units: dolosse,Accropods,hollow-square and stones are tested under five angles of wave attack:0°,15°,30°,45° and 60° for both long-crested waves and directional waves.A method is proposed to take into account the effects of wave obliquity and multi-directionality on the armour unit stability.
