Design and study of right bank flood protection dike in urban area of Ningming County

宁明县城区右岸堤防工程是宁明县城区防洪体系的重要组成部分,是城区右岸建设发展的基础。文章分析了宁明县城区右岸防洪堤工程的地质条件及周边筑堤材料的储备情况,从技术、经济、生态等方面对3种堤型进行比选,推荐粘土心墙堤型方案,并对推荐的堤型结构安全做了较详细的分析计算。

As a key component of the urban flood protection system of Ningming County,the right bank dike project is the foundation for the construction and development of the right bank urban area.Analysis was made on the geological conditions and the reserve of surrounding construction materials.Three dike types were compared in respects of technology,cost and ecology,based on which the clay core wall dike type was recommended and analyzed with a detailed structural safety calculation.
