摘　　要：拉寨水库地处方村向斜与耕者背斜之间的单斜构造带。库区内河流两岸陡峭,以“V”型谷为主,岩溶地层分布广泛,存在左岸区域性断裂,水库正常蓄水后很可能产生严重的渗漏问题。文章将利用岩溶泉点、地层岩性、钻孔资料等分段分析论证水库的成库条件,为岩溶地层发育地区工程提供参考。Lazai reservoir is located in Monocline structural zone between Fangcun syncline and Gengzhe anticline.Rivers in the reservoir area is steep,to“V”type of valley-based,karst stratigraphy is widely distributed,there is a regional fracture in left bank,the reservoir is likely to have serious seepage problems after normal reservoirs.The paper will use karst spring point,stratigraphic lithology,drilling data to sectional analysis and demonstrate conditions for building reservoir,and provide reference for projects in karst development area.
