摘要
通过地质学、岩溶动力学、构造学、地球物理勘探、流体动力学、水文地质试验、水文地球化学及同位素分析等方法,分析了三姑泉域岩溶地下水赋存与富集规律,阐明了可溶岩与构造对岩溶地下水分布的控制;采用多种手段联合方法对三姑泉域的地下水子系统进行了识别。共划分了东丹河、丹河、高平-晋城、赵庄四个地下水子系统。每个子系统内都发育强径流带,径流带内物探结果显示低电阻率,水化学显示低TDS,同位素显示高δ18O、δD值,子系统边界上则呈现了高电阻率,高TDS及低δ18O、δD值的特征。多种研究方法相互印证结论一致,提高了地下水子系统识别的准确度。
The law of karst groundwater occurrence and enrichment in the Sangu spring area was analyzed using methods of geology,karst dynamics,tectonics,geophysical exploration,fluid dynamics,hydrogeological test,hydrogeochemistry and isotope analysis,and the control of soluble rock and structure on the karst groundwater distribution was explored. Four groundwater subsystem,dongdanhe,danhe,gaoping-jincheng and zhaozhuang,in the Sangu spring area was identified by a combination of several methods. The system boundaries were found between each of the subsystems,and in each of the subsystems,a strong runoff zone was developed. Low resistivity of Geophysical exploration results,low TDS of hydrochemistry,and high δ18O,δD values were shown in the main runoff belt,while high resistivity,high TDS level and low δ18O,δD values were presented at the subsystem boundary. A variety of research methods verified the consistency of conclusion and improved the recognition accuracy.
