摘　　要：针对大连某护岸工程平面布置方案,通过波浪三维稳定物理模型试验,分别对工程前设计波浪要素和斜坡护岸稳定性进行了研究。研究结果表明,特定地形条件下近岸处波高会大于深水处波高,值得设计特别注意;采用同样重量的护面块体,在击岸破碎波的作用下,浅水段的护岸稳定性不及深水段,底部块体的失稳会导致上部块体的下滑、坍塌,从而使断面失去防浪功能;在某些情况下,斜向浪对扭王字块护面块体的作用比正向浪偏于危险。因此,工程设计需要特别注意斜向浪和击岸破碎波的影响。A 3D physical model test was carried out for a revetment project in Dalian. The design wave height and stability of slope revetment were researched based on the wave physical model. The results show that the wave height in nearshore area will be larger than that in deep water area in specific circumstance, and the stability of armor block with the same weight in shallow water will get worse under the impact of shore-strike breaking wave. The instability of block at the bottom leads to the declining and collapse of the upper block, and the oblique wave is more dangerous than positive wave for accropode armor block. Therefore, more attentions should be paid on the impact of oblique wave and shore-strike breaking wave in project design.
