摘　　要：根据调查,渝怀铁路歌乐山隧道排水引发的地下水环境负效应主要包括区域地下水位下降、地表人居饮水困难、农业生产条件改变和地面塌陷等。利用岩溶隧道地下水环境负效应评价指标体系对该隧道排水的地下水环境负效应进行评价,其结果以Ⅳ级为主,综合反映出该隧道排水产生的地下水环境负效应较强,与调查结果基本一致。上述评价工作不仅可为该隧道防排水管理提供参考,也可为类似隧道工程的选址提供科学依据。Environmental negative effects resulted by Geleshan tunnel drainage are found mainly including regional groundwater levels drawdown, being difficult to find drinking water and maintain agricultural production as well as surface collapse. An index system is used to assess the negative effects on groundwater environment resulted by tunnel drainage of Gelesha tunnel. The result shows that it gets a grade of IV, which is in accord with the investigation, synthetically reflecting that the local groundwater environment has been influenced by the drainage of Geleshan tunnel. The assessment can not only offer some reference on the management of the tunnel＇s waterproof and drainage, but also supply scientific basis for choosing a tunnel＇s location.
