摘要
五指山隧道为沐新二级公路上的特长隧道,水文地质条件十分复杂。施工中利用多种勘察手段查明隧道水文地质条件,并对膏岩地层这一特殊不良地质灾害采取了加强支护、分区排水等综合处治措施,确保了施工和营运结构的安全。本隧道建设过程中取得的经验和教训,值得类似工程参考借鉴。
Wuzhishan Tunnel is a super-long tunnel on the secondary class Muxin Road. Many kinds of investigation measures were used to find out the hydro-geological conditions of the tunnel. Against gypsum and salt rock formation comprehensive treatment measures of reinforced support and partitioned drainage were taken to successfully treat this geological hazard encountered in construction. The tunnel construction experience gained and lessons learned are helpful to similar projects.
