| 摘 要： | 通过物理模型试验,研究不规则波作用下、斜坡堤采用随机摆放扭王字块体时,波浪周期、堤顶高程改变对斜坡堤上前坡、堤顶及后坡上扭王字块体稳定性的影响。试验结果表明:随着波浪周期的变大,前坡扭王字块体稳定性逐渐增大,堤顶和后坡扭王块体稳定性反而减小,波浪对斜坡堤扭王护面的破坏位置由前坡向堤顶和后坡转移。同时,前坡扭王字块体稳定性随着堤顶超高的增加而减小,堤顶和后坡扭王块体随着堤顶超高的增加先减小后增大。

| Abstract: | Through physical model experiment,we study the influence of the change of embankment top elevation and the wave periodic on the stability of the front,the top and the back sections of the sloping dike under irregular wave and when the slope embankment is randomly arranged with the accropode blocks.The test results show that with the increase of wave period,the stability of the former slope is increasing and the stability of the crown and the back slope is reduced,and the damage position of the slope dike is shifted from the front slope to the dike top and the back slope.Meanwhile,the stability of accropode blocks of the front slope decreases with the increase of the height of the dike roof,and the crown and the back slope reduce firstly and then increase with the increase of the super height of the dike roof. |
