中文摘要	深切河谷附近岩溶地区地表水快速下渗,岩溶地下水深埋且集中径流,导致水资源匮乏,易成为较干旱缺水地区。同时在该类地区,受地表水构成的地下水排泄基准面控制,地下水水位埋深大,且以快速的管道流和裂隙流为主,储存空间分布和相互间连通性高度不均匀给打井找水带来了极大困难。发现下伏碎屑岩、逆断层和上覆碎屑岩均能将岩溶地下水和深切河谷地表水之间水力联系切断,导致局部富水,成为打井找水有利靶区。基于此3种类型,结合打井找水成功实例,将其归纳为3种打井找水模式:下伏碎屑岩隔水模式、逆断层阻水模式和上覆碎屑岩阻水模式,这些模式将对在深切河谷附近岩溶地区打井找水提供帮助。
英文摘要	Surface water rapidly infiltrates in karst area near deep river valley,and karst groundwater is deeply buried with concentrated runoff;therefore,water resources shortage near deep river valley is serious,which leads to the formation of arid areas. At the same time,in this area,influenced by groundwater discharge surface controlled by deep valleys,groundwater flow is mostly in quick pipe and fracture;storage space distribution and the connectivity of each other bring great difficulties to drill well for searching groundwater. The authors discovered that the underlying clastic rock,reverse fault and overlying clastic rock can cut off the relationship between karst groundwater and deep valley surface water,which lead this area to be local rich water and become the favorable target area for water drilling. Based on the 3 types,with the successful examples,it is classified into 3 water drilling models:the underlying clastic rock water model,inverse water resistance model,and overlying clastic rock water blocking model. These models will give some helps for water drilling in karst area near the deep valley.
