摘　　要：现行隧道规范规定隧道工程中的地下水处理必须遵循"防、排、截、堵结合,因地制宜,综合治理"的原则,但在工程实际中大多采取以排为主的处理方法。分析隧道排水可能导致的不良环境地质效应,并辅以工程实例,探讨缓解、消除不良环境地质效应的途径;倡导在隧道选线、设计、施工各个环节中将隧道地下水合理处理作为重要因素考虑,探询更为环保科学的施工方法,以缓解隧道开挖和排水所引发的不良环境地质效应。The present tunnel norms demand to take＂choking up as the main,combining waterproofing with drainage,adjusting measures according to the local conditions and comprehensive treatments＂as the treatment principles in the groundwater treatment.But most engineering projects take the drainage as the main method.Based on the analysis of geo-environmental effect caused by the drainage of groundwater and application cases,to discuss the means to relieve and solve the geo-environmental effect problems and consider the reasonable drainage of groundwater in the tunnel engineering as an important factor in the selection,design and construction of tunnel engineering.Take more scientific environmental construction methods and resource-saving treatment model to relieve the bad geo-environmental effect caused by tunnel excavation and drainage of groundwater.
