摘　　要：喀斯特地质是隧道建设常见的一种不良地质,尤其是在城市轨道建设中,喀斯特往往会引起坍塌、冒顶,威胁人们的财产及生命安全。为确保隧道安全施工,文章以贵阳市轨道交通隧道开挖为例,采用等值反磁通瞬变电磁法、隧道超前地质预报法对隧道喀斯特进行了综合预报,通过资料解释及现场开挖验证,表明针对浅层隧道喀斯特探测,等值反磁通瞬变电磁法结合隧道超前地质预报,能真实客观地反映喀斯特的发育形态及规模等情况,这一预报体系将为城市轨道建设中的隧道喀斯特问题带来新的解决方案。Karst geology is a common adverse geology in tunnel construction,especially in urban rail construction.Karst often causes collapse and puking,threatening people's property and life safety.In order to ensure the safe construction of the tunnel,this paper takes the excavation of the rail transit tunnel in Guiyang as an example,and uses the opposing-coils transient electromagnetics and the tunnel advanced geological prediction method to comprehensively predict the tunnel karst.Through data interpretation and on-site excavation verification,it shows that for karst detection in shallow tunnels,the opposing-coils transient electromagnetics combined with the tunnel advanced geological prediction can truly and objectively reflect the development form and scale of karst.This prediction system will bring new solutions to tunnel karst problems in urban rail construction.
