| 摘 要： | 铁路隧道排放地下水对隧道区域生态环境和人居环境的影响日益受到重视。在阐述监测等级、监测范围、监测对象和方法等的基础上,探讨了铁路隧道地下水环境动态监测体系,并在国内某货运铁路进行了系统实践。通过对48座隧道143处监控点位近3个水文年的系统监测,发现了34处隧道施工造成的失水水源点位;以典型隧道为例,总结说明黄土丘陵地区、基岩山区和岩溶地区监测结果,并讨论监测体系应用效果。

| Abstract: | The impact of underground water discharged from railway tunnels on the ecological environment and human settlement environment in the tunnel area has been paid more and more attention.On the basis of expounding the monitoring grade,monitoring scope,monitoring objects and methods,this paper discusses the dynamic monitoring system of underground water environment in railway tunnels,and has carried out systematic practice in a freight railway in China.Through systematic monitoring of 143 monitoring points in 48 tunnels for nearly 3 hydrological years,34 water loss source points caused by tunnel construction were found.Taking a typical tunnel as an example,the monitoring results in loess hilly region,bedrock mountainous region and karst region are summarized and explained,and the application effect of the monitoring system is discussed. |
