摘　　要：在隧道施工所遇到的不良地质中,岩溶地质是最常见也是最难处理的地质类型之一,若岩溶地质处理方法不当,将会给隧道安全施工带来极大的影响。以安六铁路大用隧道岩溶地质施工为背景,通过揭示岩溶形态及所处位置的特点,分析了隧道岩溶及涌水成因,介绍了隧底大量不规则串珠状空腔型溶洞施工情况及相关问题处理方法,通过采取加强支护结构变形控制、桩筏结构隧底处理、增设泄水洞和地表溶蚀漏斗、设置洞内结构防排水系统等多种措施对溶洞隧道涌水进行处理,结果表明采用的岩溶涌水处治技术切实有效,供类似工程参考借鉴。Karst geology is one of the most common and difficult geological types encountered in tunnel construction.If the karst geological treatment method is not appropriate,it will bring great influence to tunnel construction.Based on the karst construction of the Dayong Tunnel of the Anyu-Liupanshui railway,by revealing the characteristics of karst morphology and location,this paper analyzed the causes of karst and water gusher in the tunnel,introduced the construction situation of a large number of irregular beaded caverns at the bottom of the tunnel and the treatment methods of related problems,by strengthening deformation control of supporting structure,tunnel bottom treatment of the pile-raft structure,adding drainage tunnel and surface corrosion funnel,setting up internal structure drainage system and other measures to deal with water gushing in karst tunnel.The results show that the karst water gushing treatment technology is effective and can be used for reference in similar projects.
