摘要
在介绍青云山隧道地质与水文地质条件的基础上,以F3断层带为重点研究对象,从分析常规元素和(87Sr/86Sr、D1、8O、T)同位素水化学特征入手,探讨地下水与河水的关系,运用氚同位素测试结果,计算地下水生成的相对年龄,分析该断层带的涌水条件;采用降雨入渗法、解析法、氚同位素法预测断层带的涌水量,将计算结果进行对比,认为:氚同位素法从理论上比其它两种方法适合火山岩地区断层带的涌水量计算。
Based on the geological and hydrogeological conditions of Qingyunshan tunnel,mainly focused on the F3 fault,this paper begins with the analysis of hydrogeochemical characteristics of common elements and(^87Sr/^86Sr、D、^18O、T)isotopes,and studies the relationship between the groundwater and the surface water,then by using tritium test results,the relative age of the groundwater is calculated and water yield condition is analyzed;the hydraulic discharge in the fault is predicted by the rainfall infiltration method,analytical method and tritium isotope method,and the calculated results are compared.The conclusion is that the tritium isotope method is theoretically more fitted for the calculation of hydraulic discharge in the fault of volcanic rock zone than the others.
