摘要：

本文介绍宜万铁路某隧道采用氯化钠为示踪剂进行地下水源调查，分析隧道突水与暗河之间的关系。通过测定接收点暗河水的电导率和氯离子浓度随时间的变化关系，确定了小马滩—龙潭—蝌蚂口暗河走向关系，同时也证明隧道突水点与该暗河无明显的直接水力联系。

Abstract:

The groundwater investigation for a tunnel on YichangWanzhou railway by using NaCl as an artificial tracer is presented in the paper. The relationship between the water gushing in the tunnel and the underground rivers is analyzed. By measuring the electrical conductivity and chloride concentration of the water at the monitoring points, the direction of XiaomatanLongtanKemakou underground river is determined and it is verified that there is no direct relation between the water gushing in the tunnel and the underground river.

Key words: artificial tracer test, underground river, chloride, groundwater investigation
