| 摘 要： | 以浙江舟山某海岛高滩陡坡地形下的电力设施海堤为例,通过物理模型试验,分别研究了平台宽度、平台超高、防浪墙高度对海堤越浪量的影响,并采用方差分析法进行了敏感性分析。结果表明:平台超高对越浪量的影响最为显著,防浪墙高度次之,平台宽度影响最小;无量纲形式下的越浪量随防浪墙顶超高的增大呈现较明显的指数递减关系。据此提出了电力设施海堤防浪结构的合理设置方式。

| Abstract: | Taking the seawalls of power facilities in the high shoal and steep slope topography of an island in Zhoushan, Zhejiang as an example, 3 factors that influence the seawall overtopping rate, including the berm width, the berm superelevation and the height of the parapet wall were studied respectively by physical model experiment and sensitivity analysis was carried out by the method of variance analysis. The results show that the most significant influencing factor of the wave overtopping is the berm superelevation, then the height of the parapet wall and the berm width is the least. The dimensionless wave overtopping rate exhibits obvious exponential relationship of decrease with an increase for the top of the parapet wall superelevation. A reasonable layout method of the seawall structures for power facilities is proposed based on the above analysis. |
