恩施某水库坝址选择方案分析

某拟建水库位于鄂西褶皱山地，坝址区地形、地质条件复杂，为了优选拟建坝址，结合地形地貌、地层岩性、地质构造及库区渗漏等条件，并且考虑施工条件与筑坝工作量，对拟选上、中、下3个坝址方案进行了对比。结果表明：上坝址的地形地质条件较好，大坝的稳定问题不突出，边坡稳定性较好，渗漏不严重，开挖工程量亦较少，故推荐上坝址为该水库坝址。

Analysis on selection scheme of dam site for a reservoir in Enshi administrative area

Due to the location of a reservoir to be constructed in folded maintain land in the west of Hubei Province,the topographic and geologic conditions are complex.In order to select the best dam site,combining with the conditions such as reservoir topography,lithology,geological structure and reservoir seepage,three proposed dam site schemes are compared considering construction condition and workload of dam construction.The results show that the dam site of the reservoir recommended to construct on the upstrea...
