摘要
贵州水柏铁路何家寨隧道,工程地质条件极其复杂,集“高瓦斯、强岩溶、大涌水”为一体,施工期间曾发生多次涌水涌砂、洞内坍方、地表塌陷与滑坡、支护衬砌开裂变形等地质灾害,堪称水柏铁路施工难度最大的“烂洞子”。文章结合该隧道地质灾害的整治实践,就有关设计与施工技术问题进行探讨。
The geological conditions are very complicated in Hejiazhai tunnel which is located in Guizhou Shuibo railway, this tunnel is named “mashed tunnel” with the most difficult geological conditions such as the high dense gas and developed karst and gushing water assembled together, the geological hazards like the gushing water and sand, the collapse of tunnel, surface subsidence and slide, cracking of tunnel lining were often happened during construction period. The author researched the related technical issue according to the remedial practice for the geological hazard of this tunnel.
