摘要
对比万坝水库主库混凝土面板堆石坝和沥青混凝土心墙坝2种坝型方案,面板坝在地形地质适应性、枢纽布置、施工条件和投资经济性等方面均较心墙坝优越。结合地质勘探揭露成果,围绕首部枢纽布置、坝顶高程、坝体结构体型、坝基处理等关键技术问题进行深入研究。论证结果表明,优选的面板坝方案,其地形地质适应性强、首部枢纽布置及坝体体型参数设计合理,可为工程施工提供强有力的技术支持。
Compared with the two dam types of concrete face rockfill dam and asphalt concrete core dam in Wanba reservoir,the concrete face dam is superior to the core dam in topographic and geological adaptability,hub layout,construction conditions and investment economy.Based on the results of geological exploration,this paper makes an in-depth study on the key technical problems,such as the layout of the first hub,the elevation of the dam crest,the shape of the dam structure,and the treatment of the dam foundation.The demonstration results show that the optimized concrete face dam scheme has strong topographic and geological adaptability,reasonable layout of the first hub and reasonable design of dam shape parameters,which can provide strong technical support for engineering construction.
