摘　　要：通过物理模型试验,研究在不规则波作用下斜坡式护岸护面采用扭王字块体时,摆放方式、摆放密度和坡度对扭王字块体稳定性的影响,给出不同摆放形式的护面层空隙率P以及不同摆放形式、摆放密度和坡度所对应的稳定系数KD的取值范围,并对越浪量进行对比分析,为工程设计提供参考。By physical model experiment which is performed under irregular wave and adopts accropodeblocks on a sloped revetment, we study factors which affect the stability of accropode blocks including mode ofplacing, placing density, as well as the slope gradient, and obtain the void ratio of the revetment P under differentmodes of placing.We also give the value range of stability parameter KD under different placing modes of accropodeblocks, density of accropode blocks and slope gradient. In addition, overtopping data is also analyzed, which mayserve as reference for future design.
