摘要
贵州省雷山县鸡鸠水库工程场区所处大地构造单元为华南褶皱带,库区分布地层主要为下江群番召组及第四系,番召组岩层主要为非可溶的变质岩,第四系主要为残坡积层和洪冲积层。在分析区域地质背景及库区、坝址区工程地质条件基础上,结合库岸边坡、水工布置、淹没影响及交通条件等,进行了坝址比选,最终推荐在下坝址位置修建大坝的方案。
Jijiu reservoir in Leishan, Guizhou province is located in the Huanan fold belt, the main lithology in reservoir area is Fanzhao team and Quaternary, and the Fanzhao team lithology is mainly unsoluble metamorphic rock, the Quater- nary lithology is mainly eluvial and slope soil, alluvial and proluvial soil. Based on the analysis of regional geological background and engineering geological condition of reservoir and dam area, according to the comparison of upper and un- derside dam site＇s reservoir slope, hydraulic architecture, inundation, and traffic condition etc. the dam site selection is carried out. the author recommends the scheme of building the dam in underside dam site.
