摘　　要：岩溶广泛分布于我国西南地区,如何解决软弱围岩复杂岩溶段隧道施工的问题是隧道建设的关键。以金口河隧道为背景,介绍了岩溶路段的处理原则,结合岩溶的类别和规模、岩溶水发育情况、岩溶空洞与隧道的位置关系等提出相应的施工技术,研究成果可为同类工程建设提供经验参考。Karst widely distributesin southwest of China. How to facilitate the tunnel construction in complex Karst areawith weak surrounding rock is a key scientific problem. Taking Jinkouhe Tunnel as the background, this paper introduces the treatment principle of karst area, and puts forward the corresponding construction technology according to the category and scale of karst, the development situation of karst water, the position relationship between karst cavity and tunnel. The research results can provide experience reference for similar engineering construction.
