摘　　要：水电工程有限的勘察及水文地质钻探仅能获取少量水文地质信息 ,而在工程勘察特别是平硐中 ,易取得出水点的水样 ,通过水化学分析可以获得更多的水文地质资料。通过对四川省自一里水电站平硐出水点水化学样的系列采集和测试 ,运用水化学成分离子比例分析法、灰色关联分析法和D、18O同位素分析法等多种方法提取了平硐区水文地质信息 ,分析了山区平硐裂隙水的来源、补给高度及岩层渗透性等水文地质特征 ,探讨了水化学分析方法在分析水电工程水文地质条件中的应用。Since little hydrogeological information can be obtained from limited hydrogeological drilling and hydropower engineering survey. In the engineering geological investigation, especially in the adits, water sampling is readily available and more information can be obtained from hydrochemical analysis of water samples. In this paper, a series of water samples have been sampled and measured. More hydrogeological information about the source of fractural water, recharge altitude and the penetrability of terranes has been gained by ions ratio analysis, gray relation analysis and D & 18O isotopes analysis. The hydrochemical analysis is available to hydrogeological analysis in the hydropower engineering.
