| 摘 要： | 基于ADCIRC建立了三门湾风暴潮模型,模型模拟结果与实测数据吻合较好。以可能最大热带气旋参数为基础构建了多种假想台风路径来计算三门核电厂址处的可能最大风暴潮增水。结果表明,NW向登陆且距离核电厂址左侧为R(最大风速半径)时的假想台风使得三门核电厂址处的增水达到最大,风暴潮增水最大值为4.58 m。将可能最大风暴潮增水叠加天文高潮位进行计算,厂址前沿处水位达到了7.75 m,而三门湾顶附近的最高水位已经达到9 m,超出了三门湾沿岸海堤高程。将三门湾沿岸陆地依照高程概化为计算区域进行漫堤计算,当天文高潮位叠加可能最大风暴潮水位时,三门湾沿岸会发生漫堤溢流现象,淹没范围最严重的区域出现在湾顶处,最大淹没面积达到了120 km2。此时厂址前沿最高潮位为7.25 m,与不溢流相比下降了0.50 m。本研究可为三门核电厂址的安全防护提供科学依据。

| Abstract: | A storm surge model for Sanmen Bay was established based on ADCIRC and the model simulation results were in good agreement with the measured results. A variety of hypothetical typhoon paths using possible maximum tropical cyclone parameters were built to calculate the possible maximum storm surge at the plant site. The results showed that the north-west landfalling path to the left of site by maximum wind speed radius caused the maximum storm surge level by 4.58 m at the site of sanmen nuclear power plant. When the possible maximum storm surge was added to high tidal level, the total level reached 7.75 m at the front of nuclear plant site and 9.0 m near the top of the Sanmen Bay which exceeded the seawall height along the Sanmen Bay. The land area was generalized to overflow calculation. The water overflowed the dam when the PMSS met high tidal level and the most serious inundation happened at the top of the bay. The maximum inundation area reached 120 km2. The extreme sea level at the front of the plant site was 7.25 m, which was 0.50 m lower than that without overflow. The results could provide scientific basis for the protection of the sanmen nuclear power plant. |
