| 摘 要： | 对广西沿海各验潮站重现期高潮位进行了计算,通过分析传统重现期高潮位计算方法发现该局限性主要为广西全日潮潮汐性质下天文潮与风暴增水叠加概率过低和广西沿海堤防标准普遍偏低所致。根据不同岸线类型,结合海堤实际防御能力、海洋灾害承灾体和风险区划,提出适用于广西的红色警戒潮位核定新方法,对其它全日潮岸段警戒潮位核定和防潮应急管理等提供新的思路。

| Abstract: | This paper calculates the high tide level with different return periods for each tide stations in Guangxi.The limitation of traditional method in calculating high tide level with different return periods is caused by the low probability for the astronomical tide overlaying storm surge and the low standard for seawall in Guangxi.Based on the different types of coastline in Guangxi, a new method in approving the warning tide level in red is proposed by considering the defensive capacity of seawall, marine disaster-bearing bodies and risk zoning.,which provides a new approach for approving warning tide level and the emergency management in other diurnal tide regions. |
