摘　　要：某水库位于县城西郊胡家庄村的淮河干流上、县城西北2 km处,控制流域面积64.20 km^(2),坝址区以上河道长度22.10 km,多年平均径流量2 589万m^(3)。水库工程任务以防洪为主,结合灌溉、供水等综合利用。文章对上坝址和下坝址在地形地貌、地层岩性、构造、覆盖层厚度、风化带厚度、透水带深度、岩体质量等进行对比分析,上、下两个坝址的基本工程条件相似,各有优劣,均具备建坝条件,上坝址在地形方面及搬迁人口方面优于下坝址。The planned reservoir is located on the main stream of the Huaihe River in Hujiazhuang Village,2 km to the northwest of the county seat,with a control area of 64.20 km^(2).The river length above the dam site is 22.10 km,and the average annual runoff is 25.89 million m^(3).The construction of the reservoir project is mainly for flood control,combined with irrigation and water supply.This paper compares and analyzes the topography,stratum lithology,geological structure,overburden thickness,weathering zone thickness,permeable zone depth,rock mass quality and so on of the upper dam site and lower dam site.The basic engineering conditions of both sites are similarly,and are suitable for dam construction.Considering the topography and relocation of residents,the upper site is better than the lower site.
