摘　　要：兰西水库工程区水文地质情况复杂,厚覆盖层堆积和强风化溶蚀带共存于库区。为确保设计方案整体优良,结合工程地质和水文地质勘察结果,对坝址区的主要地质问题和坝型匹配性进行详细论证分析。设计优选的上坝址重力坝坝型方案,工程地形地质适应性强、枢纽布置紧凑、边坡稳定性好,技术可行且经济。兰西水库坝址区详细的工程地质评价,可为枢纽布置、坝基及两岸防渗处理等提供准确的地质资料和处理建议,也可为岩溶地区修建水库提供借鉴参考。The complex conditions of topography and geological with thick overburden accumulation and strong weathering corrosion zone is coexisting in the reservoir area of Delong reservoir.In order to ensureoverall optimization the design scheme,the main geological problems in the dam site area and the dam type matching have been compared and demonstrated in detail combination with the engineering geology and hydro-geological survey results.The optimization gravity dam type scheme at upper dam has strong topographic and geological adaptability,compact hydro-project layout,good slope stability,and is technically feasible and economical.The detailed analysis of engineering geological conditions in the dam site which can provide important geologic data and proposed conclusions for hydro-project layout,dam foundation and both banks anti-seepage treatment of Lanxi Reservoir,and it can also provide some reference for the reservoirs construction in karst areas.
