通过对三塘湖盆地水文地质结构、地下水类型及富水性特征分析,讨论地下水赋存分布特征,为当地矿产资源开发及供水水源地建设提供水文地质依据。采用水文地质钻探、物探、测绘、抽水试验及测试等方法获取基础水文地质数据,对储水介质岩性和厚度、含水层特征、富水性等空间变化规律归纳总结,认为盆地内具单一结构松散岩类孔隙潜水、多层结构孔隙潜水-碎屑岩类孔隙裂隙承压水、碎屑岩类孔隙裂隙承压水的赋存分布特征。
By analyzing the characteristics of hydrogeological structure, groundwater types and water-rich features in the Santanghu Basin, the paper discusses the characteristics of groundwater occurrence and distribution and provides hydrogeology basis for the development of local mineral resources and the construction of water supply sources. Basic hydrogeological data were obtained by means of hydrogeological drilling, geophysical prospecting, mapping, pumping test and testing, and the spatial variation rules of lithology and thickness of aquifer, aquifer characteristics and water-richness were summarized. It is concluded that there is loose single structure Rock pore water diversion, multi-layer pore-submersible-clastic rock pore water pressure fracturing water, clastic rock pore water pressure confined water occurrence and distribution characteristics.
