采用JONSWAP谱,以不同波浪入射方向对大连海上机场人工岛护岸结构进行了整体波浪物理模型试验。试验表明,对于设计给出的斜坡护岸形式,在极端高水位、波浪重现期为100 a和200 a的情况下,布置于东侧、北侧和西侧护岸护底块石、胸墙、扭王字块分别为3、5、7 t时均能够保持稳定。这一试验结果为人工岛护岸结构的优化提供了科学依据。
Using JONSWAP spectrum, the experiment on the whole physical wave model of revetment structure of Dalian offshore airport artificial island is carried out with different wave direction. Experiments show that the designed slope revetment types can keep stable in the case of extreme high water level and wave return period of 100 a and 200 a, when the bottom-protecting rubble, breast wall and accropodes in the eastern, northern and western of revetment are respectively 3 t, 5 t and 7 t. The experimental results provide a scientific basis for optimizing the artificial island revetment structure.
