摘要: 

通过对前人在北山地区已经进行的钻孔取样分析测试及野外调查资料进行归纳总结,获得了目前所研究的北山地区具有代表性的水样化学组成。结果表明,北山旧井地段3号钻井获得的水样成分可以代表北山地区的地下水总体情况,其中Na+,Cl-和SO42-含量最高且差别不大,而K +和NO3-含量普遍较低,含量较高组与含量较低组相差近4倍。Cl-和SO42-一直是影响腐蚀程度的重点因子,甘肃北山地区代表性地下水成分的确定为以后进行北山地区高放废料储罐表面化学环境的模拟和储罐腐蚀研究奠定了基础。

关键词 北山地区地下水成分地质处置储罐腐蚀    
Abstract

Based on the data of previous analysis of groundwater samples by bore holing and the data of the field survey in Beishan area, the chemical compositions of the typical samples collected from ground waters in the desired sites were summarized in this paper. It can be drawn after a comparative evaluation of the content of the main anions and cations of ground waters that the groundwater sample collected from the third borehole in the Jiujing block can be considered as the representative of ground waters of Beishan area, therefore, which may be adopted in the near future as a medium for corrosion evaluation of candidate materials to provide a near-field chemical environment around the disposal waste container in high-level radioactive waste disposal repository of Beishan area.

Key wordsBeishan area    groundwater composition    geological disposal    container    corrosion
