摘要:
海堤是保护我国近海生命和生产安全的重要屏障，海堤的防御能力的评估具有重要的实际应用意义。本研究考虑海堤对海水入侵的防御内在属性，从堤身材质、护面块体、底基地质、防浪配置和堤顶高程这五个指标因子建立海堤防御评估指标体系，采用层次分析方法，得到各指标因子的指标权重值，构建了海堤防御能力评估模型。对江苏、山东沿海海堤进行了灾害实例分析评估。结果表明，对海堤的防御能力评估结果与其在海洋动力灾害过程期间的实际防御表现基本一致。

Abstract:
A seawall is an important barrier to protect the life and safety of production along the coast lines and, therefore, it is of practical use to adequately assess the seawall's active defense capacity. In this study, we considered intrinsic attributes of the seawall's defense capacity, including body material, dike dam block, base load, wave configuration and elevation of the top of the seawall to establish the seawall defense assessment index system. A model for assessing the defense capability of the seawall is proposed, using the hierarchical analysis method to obtain the index weight of each index value. The results show that the assessment result is basically consistent with the actual performance of the defense during the dynamic marine disaster process.
