摘　　要：贵南高铁朝阳隧道出口穿越岩溶地层,2018年6月10日曾发生严重透水事件,给隧道后续施工带来巨大安全隐患。基于此,文章对朝阳隧道出口地表岩溶和地下暗河的发育特征开展地质调查,探明了“6·10”突水事故的成灾原因为暗河突涌;并根据现场工程情况,对比分析了三种洞内溶腔处理方案和四种出口排水方案,提出了岩溶突水灾害整治措施。研究成果对贵南高铁隧道后续施工过程中突水风险控制,具有重要的参考价值。The exit of Chaoyang Tunnel of Guiyang-Nanning High-speed Railway passes through karst strata. On June 10, 2018, a serious water seepage accident occurred here, which brought great potential safety hazards to the subsequent construction of the tunnel. Based on this, this paper carries out geological survey on the development characteristics of surface karst and underground river at the exit of Chaoyang Tunnel, and finds out that the cause of "6·10" water inrush accident is underground river inrush.According to the field engineering situation, three kinds of cavern treatment schemes and four kinds of outlet drainage schemes are compared and analyzed, and the treatment measures of karst water inrush disaster are put forward. The research results have important reference value for water inrush risk control in the subsequent construction process of Guiyang-Nanning High-speed Railway tunnel.
