高放废物处置库北山预选区泉水成因分析

Origin analysis of springs in Beishan preselected area for China's high level radioactive waste repository

文章通过前人资料的分析,结合水文地质调查工作,探讨了北山地区泉水的成因,认为该区分布的泉大部分是下降泉,接受潜水补给;少部分为上升泉,接受盆地地下水或断裂带地下水补给;属于北山内部的地下水循环交替方式之一,与深大断裂关系不明显。

Through analysing the data from predecessors and combined with field hydrogeological investigation, this paper discussed the origin of the springs in Beishan . it was concluded that most of the springs are recharged by phreatic water and belong to the descending springs; A few of them are recharged by pressure water coming from deep basin and fault zone and belong to the ascending springs. The spring water belongs to the internal water circulation system in Beishan area and has no obvious relation with deep and big fault.
