摘要
在超越设计的波浪作用下,扭王字块护面的护岸发生护面块体下滑、块体破损、堤心石被淘刷等破坏,引发后方陆域塌方的巨大威胁。在已经破坏的护岸上采用更大的扭王字块体进行防护是一种有效的加固方式。通常垫层石重量为护面块体的1/10～1/20,采用波浪物理模型对加固后的护岸进行稳定性试验研究,验证原块体作为垫层的适应性,结果表明有较好的稳定性。
Under the effect of larger-than-design waves, revetment with Accropode blocks has been dameged by revetment block sliding, block breakage, and even scouring of the core rocks, which causes a great threat to the stability of land area. It is an effective way to repair and reinforce the damaged revetment by using larger Accropode blocks for protection. Usually the weight of underlayer rocks are 1/10 ~1/20 of Accropode blocks. An experimental study on the stability of the reinforced revetment was carried out by using wave physical model to verify the adaptability of the original block as cushion, and the results show that it has better stability.
