基于GMS的山西辛安泉域地下含水层结构模型研究

A GMS-based Model of the Underground Aquifer Structure in the Xin an Spring Domain

辛安泉域岩溶地区存在较多岩溶管道、人工采煤巷道和复杂的地质构造等,水文地质条件十分复杂。为准确构建辛安泉域三维地表水-地下水数值模型,开展岩溶水资源承载力评价,需要精确建立辛安泉域三维地下含水层结构模型。采用GMS软件基于实际钻孔数据资料、虚拟钻孔数据和水文地质剖面资料精细建立长治市辛安泉域岩溶含水层三维含水层结构模型。结果表明,采用GMS模型,基于实际钻孔数据资料、虚拟钻孔数据和水文地质剖面资料建立的长治市辛安泉域三维含水层结构模型更接近实际,采用这种方法构建含水层结构模型能够为后期精确建立长治市辛安泉域三维地表水-地下水数值模型打下坚实的基础。

There are many karst pipelines,artificial coal mining tunnels and complex geological structures in the karst area of Xin an Spring,and its hydrogeological conditions are very complex.In order to accurately construct a three-dimensional surface water-groundwater numerical model of Xin an Spring Basin to carry out the evaluation of karst water resources carrying capacity.First,it is necessary to accurately establish a three-dimensional model of the underground aquifer structure of the Xin an Spring Area.Therefore,this study uses the GMS model to establish the three-dimensional aquifer structure model of the karst aquifer in the Xin an Spring Area of Changzhi City based on actual borehole data information,virtual borehole data and hydrogeological profile information.The results show that the 3D aquifer structure model of the Xin an Spring Area in Changzhi City,which isbased on the actual borehole data,virtual borehole data and hydrogeological profiles data,is closer to reality by using the GMS model.The three-dimensional aquifer structure model of Xin an Spring constructed by this method can provide a model basis for the later accurate establishment of a three-dimensional surface water-groundwater numerical model of Xin an Spring in Changzhi City.
