| 摘 要： | 公婆泉是我国高放废物处置库场址北山预选区众多泉中少有的淡水泉，该泉水的成因问题与处置库场址选择具有一定的关系。通过前人资料的分析，结合水文地质调查工作，探讨了该泉的成因，认为该泉是一个受潜水补给的下降泉。泉水的补给来源是位于该泉西南部的驼马滩盆地古近系一新近系下覆基岩古风化壳地下水，其水质良好、水量丰富，流向北东，经公婆泉丘陵一带后，在沟谷侵蚀含水层处溢出，形成公婆泉。

| Abstract: | Gongpoquan spring is a rarely fresh water spring among the springs in Beishan area--the preselected area for China＇s high level radioactive waste disposal repository. The origin of this spring has some relation to the site selection of disposal repository. Through analyzing the data from predecessors and combining with field hydrogeological investigation, the origin of the spring is discussed in this paper. The result shows that Gongpoquan spring is a descending spring recharged by phreatic water coming from ancient weathered crust beneath the Tertiary in Tuomatan Basin. The phreatic water is of high quality and large amount flux. The phreatic water flows from southwest to northeast. After passing through the Gongpoquan hill area, it overflows in the aquifer eroded by the gully, then forms the Gongpoquan spring. |
