黄河南海堤防潮工程护面块体选型试验研究

摘要

黄河南海堤防潮工程地处黄河三角洲,因地势平坦,缺乏石料来源,不宜采用抛石护岸及孔隙率较大的护面块体.选择混凝土平板与天龙板作为护面块体,采用水工物理模型试验进行比较研究,验证了防潮堤在不同工况的临界破碎波高作用下的护面块体稳定性.研究发现,天龙板重量较轻,消浪效果较好,整体性强,适合作为黄河南海堤防潮工程的护面块体.%Tide embankment of south seawall for Yellow River is located in Yellow River Delta. It is not suitable to utilize the ordinary armor blocks within high porosity and riprap protection because of lack of stones and flat terrain. The concrete flat plate and Tianlong plate are proposed in the present paper, the stability of armor blocks under the critical incident wave conditions within various cases using physical modeling experiments. Tianlong plate has small weightness and good integrity, which has good capability on wave absorbing. Therefore, Tianlong plate is suitable for tide embankment of south seawall for Yellow River as the armor blocks.
