摘要
为了了解八宝水库库区地下河的连通性,评价蓄水后是否会发生渗漏,2003年12月底笔者在八宝水库进行了盐示踪试验。以此为例介绍了自动化监测电导率在示踪试验中的应用。实验证明水溶液的电导率直接和溶解盐的浓度成正比,水溶液中电导率的变化反映了溶解的NaCl的变化情况。本次试验通过自动化监测仪器记录水溶液中电导率随时间的变化,反映水中溶解的NaCl随时间的变化情况。根据流量数据换算得出回收量和回收率等数据。
This paper has described the application of electric conductivity to the tracing test in Babao Reservoir in December, 2003. The electric conductivity is the mirror of the concentration of dissolved soild. The higher the dissolubility, the higher the electric conductivity. So the variation of concentration of NaCl dissolved can be recorded by the variation of electric conductivity. The curves can be obtained by the utilization of autoreadahle and autostoreable MultiP3. According to the flow rate data, such information as the amount and the rate of flow-out NaCI can be obtained.
