摘　　要：针对宜万铁路齐岳山隧道遭遇的629富水溶洞,采取超前地质探孔、放水试验、注浆试验、迂回绕行等综合手段查清了该溶洞的工程水文地质条件;通过钻孔排水和增设排水支洞排水减压措施,消除了该富水溶洞突发涌水的安全隐患;进而对溶洞实施安全爆破揭示,以及溶洞段采用加强型复合式衬砌隧道结构、复合地基等综合措施进行处理。其综合处理技术对类似工程具有重要的参考价值。In view of 629 water-rich karst cave of Qiyueshan tunnel on Yichang-Wanzhou railway,its hydrogeological conditions were explored by geological exploratory drilling,drainage experiment,grouting test and bypass adit.The risk of gushing water from the water-rich cave was eliminated by drainage measures of drilling drainage holes and ducts to reduce water pressure.By the implementation of safety blasting the karst cave was revealed.Strengthened composite lining structures,composite foundation and other comprehensive measures were adopted on the karst section.The comprehensive treatment measures are of great reference value for similar projects.
