摘要
黔东南州工业园区位于复杂的地质构造带,寒武系白云岩地层是区域地下水赋存的关键层位。本研究通过水文地质勘察、物探找水及凿井工程实践,系统分析了寒武系石冷水组与娄山关群白云岩的水文地质特征。研究结果表明,区内含水层与隔水层的划分受岩体完整性、节理裂隙发育程度及断层控制显著,地下水以岩溶裂隙水为主,补给来源为大气降水,日均入渗量达29565.70m^(3)。ZK2#深井涌水量1210.46m^(3)/d,验证了含水层划分的合理性。研究为类似岩溶区地下水资源开发提供了理论依据与工程参考。
The industrial park in Qiandongnan Prefecture is located in a complex geological structure zone,and the Cambrian dolomite strata are the key layers where groundwater occurs in the region.In this study,through hydrogeological investigation,geophysical water exploration and well-drilling engineering practice,the hydrogeological characteristics of the Cambrian Shilongshui Formation and the dolomite of the Longshanguan Group were systematically analyzed.The research results show that the division of aquifers and impermeable layers in the area is significantly controlled by rock mass integrity,the development degree of joints and fractures,and faults.The groundwater is mainly karst fissure water,and the recharge source is atmospheric precipitation with an average daily infiltration volume of 29565.70m^(3).The water inflow of deep well ZK2#was 1210.46m^(3)/d,verifying the rationality of the aquifer division.The research provides a theoretical basis and engineering reference for the development of groundwater resources in similar karst areas.
