中文摘要:
      对国内第一个岛屿地形下核电厂的护岸防洪设计进行了研究,提出直立式护岸结构方案以满足核电厂防洪和避让毗邻海岛的要求。在波浪数值模拟计算结果基础上,开展了波浪整体物理模型试验、波浪局部整体物理模型试验和波浪断面物理模型试验,对护岸的越浪量和结构稳定性进行了优化验证。研究结果表明,岛屿地形下,波浪破碎和波能集中导致护岸堤身坡脚处波高增大,须加高挡浪墙和优化挡浪墙结构型式;在相同的越浪量标准下,采用直立堤结构相对斜坡堤结构对应的护岸挡浪墙的高程须明显加高;利用部分海岛地形斜坡高地作为厂区护岸一部分时,原状海岛地形斜坡高地处的波浪爬高效应明显,须加高邻近护岸挡浪墙的高程。

英文摘要:
      The design of flood control for revetment of the first nuclear power plant built on an island in China is studied and a scheme of vertical revetment structure is proposed in order for the plant to meet the requirements of flood control and to separate from the adjacent islands. A series of wave physical model tests are carried out based on the results of wave numerical simulation, and the wave overtopping and structural stability of the revetment are verified and optimized. The results show that in the case of island topography, the wave wall should be raised and its structural type should be optimized because the wave height at the slope foot of the revetment rises due to wave breakage and wave energy concentration. Under the same standard of wave overtopping, the elevation of the wave wall of the vertical revetment structure should be increased obviously compared with that of the slope dike structure. When using some island terrain slope highlands as parts of the revetment in the plant area, the elevation of the wave walls of the adjacent revetments must be increased because the wave climbing effect is obvious at the slope highlands of undisturbed island terrain.
