摘　　要：京广铁路南岭隧道穿过灰岩地层占95%以上,勘察设计及施工中遇到了许多岩溶地质问题。系统地总结南岭隧道修建中一些成功经验,对岩溶地区修建长隧道在勘察手段、施工地质预测预报方面有一定借鉴作用;岩溶灾害地质和环境地质的严重性在设计时应引起高度重视并制定相应的对策。Nanling tunnel on Beijing-Guangzhou railway passing through more than 95 % limestone stratum,lots of karst geological problems were encountered during the survey design and construction. This article systematically summarizes the successful experiences in the construction of Nanling tunnel and makes advance in guiding the survey method,geological forecasting for constructing long tunnel in karst area. The severity of geological hazard and environmental geology in design should be paid great attention and needed to formulate corresponding countermeasures.
