基于岩溶地区地下水位移对浅层地温能开发利用的影响评价

Evaluation of the Impact of Groundwater Level Shift on the Development and Utilization of Shallow Ground Temperature Energy in Karst Regions

岩溶含水层的富水性相对较强,但岩溶水并非均匀遍及整个可溶岩的分布范围,随着地下水的采掘,形成不同范围的降落漏斗,从而引起地下水以漏斗为中心的地温异常,对工作区岩溶地区两个水源地附近的9口钻孔的地温进行长期观测,系统研究岩溶地区地下水运移影响范围内的地温场分布特征,评价地下水运移对岩溶地区浅层地温能开发利用的影响。

The water-rich property of karst aquifer is relatively strong,but the karst water is not uniformly distributed throughout the entire range of the karst,with the exploitation of groundwater,forming different areas of the drop funnel,the long-term observation of the ground temperature of 9 boreholes near two water sources in the working area of karst region was carried out,this paper systematically studies the distribution characteristics of geothermal field within the influence range of groundwater movement in karst area,and evaluates the influence of groundwater movement on the exploitation and utilization of shallow geothermal energy in karst area.
