摘要
随着我国山区高等级公路的发展和建设规模的不断扩大,山区公路隧道的建设也日益增多。隧道工程作为整个工程的控制性因素,由于冒顶引起的工期延误、经济损失甚至人员伤亡给工程带来不可估量的损失。文章结合贵州省盘兴高速公路某隧道冒顶事故,对其原因进行分析,采取相应的加固处理措施,并采用有限元分析程序对初期支护及二次衬砌进行结构验算,实测监控数据分析表明,该处理方案行之有效,可供类似工程施工参考。
With the development and continuous expansion of construction scale in high-grade mountain highway,the construction of mountain highway tunnel is increasing. Tunnel engineering is the controlling factor of the whole project,roft collaspe of tunnel will lead to construction delay,economic losses or even casualties. Combining with the tunnel roof callaspe accident of Panxing expressway in Guizhou province,it＇s causes are analyzed and corresponding reinforcement measures are used,the finite element program is used to check the structure of initial support and secondary lining. The actual monitoring data show that the treatment measurs are effective and could provide reference for similar incidents.
