摘　　要：结合苏北滨海海域实际海堤防护工程,通过波浪断面物理模型试验,对柔性混凝土铰链排和刚性混凝土槽型块两种护坡形式分别展开各海堤断面中消浪平台及以上堤身结构在规则波及不规则波作用下的波压力研究,并比较分析两者之间的差异。试验结果表明,铰链排护坡对消减波能的效果要优于槽型块护坡,更有利于海堤的安全性和稳定性。同时根据波压力分析结果对混凝土铰链排护坡式海堤提出了相应的优化加固措施。Combined with the instance of practical seawall protection project in Binhai sea area of NorthJiangsu province, we explore the wave pressure on wave dissipation platform and seawall structure above the platformunder the action of regular and irregular waves in the case of flexible hinged concrete slab mattress revetment andrigid concrete groove block revetment respectively through wave section physical model experiment, and compare thedifferences between them. The experimental results show that hinged concrete slab mattress revetment does betterthan concrete groove block revetment in reducing the wave energy and is more conducive to security and stability ofseawall. Moreover, corresponding optimization and reinforcement methods for seawall with hinged concrete slabmattress revetment are put forward according to the analytical results of wave pressure.
