摘要
为研究不良地质条件下隧道施工与监测技术,以重庆城口~开州高速公路旗杆山隧道工程为例,首先分析旗杆山隧道所处地质环境给工程施工带来的重难点,进而对隧道总体施工方案进行研究,并依次针对工程存在的重难点对隧道的断层及破碎带、大变形及岩爆段以及瓦斯段的具体施工方案进行研究,最后对隧道的监测方案进行研究,提高了施工质量与施工安全的可靠性。
In order to study the construction and monitoring technology of tunnels under unfavorable geological conditions,taking the Qiganshan tunnel project of Chongqing Chengkou to Kaizhou Expressway as an example,the difficulties brought by the geological environment of the Qiganshan tunnel to the engineering construction are firstly analyzed,and then the difficulties for the tunnel construction were analyzed.The overall construction plan is studied,and the specific construction plans of the tunnel's faults and broken zones,large deformation and rock burst sections,and gas sections are studied in turn according to the major and difficult points of the project.Finally,the monitoring plan of the tunnel is studied to improve the quality of construction and safety and reliability of construction.
