摘　　要：花南引水隧洞位于贵阳市花溪区,工程沿线大面积分布碳酸盐岩地层,岩溶大量发育,地下水丰富,水文地质条件复杂。岩溶涌水是本隧洞工程施工中常见地质问题,既降低了围岩稳定性,又增加了施工安全隐患。文章基于工程区地质条件,分析不同施工涌水来源,提出已揭露洞段与未揭露洞段涌水处理原则与措施,对类似引水隧洞施工及岩溶涌水处理措施等方面具有一定借鉴作用。The Huanan Diversion Tunnel is located in Huaxi District,Guiyang.The large-area distribution of carbonate formations along the project.It has the characteristics of karst development,abundant groundwater and complex hydrogeological conditions.The karst gushing water is a common geological problem in the construction tunnel.It reduces the stability of the surrounding rock and increases the hidden dangers of construction safety.The article is based on the geological conditions of the engineering area to analyze different sources of construction gushing water.Proposing principles and measures for water gushing treatment between excavated tunnel sections and will had excavated tunnel sections.Suggesting to the similar projects about the construction of the diversion tunnel and the treatment measures for karst gushing water.
