| 摘 要： | 米家寨隧道是忻保高速公路中地质条件较差的隧道之一,具有明显的浅埋和偏压的特征。本文从米家寨隧道的地形地貌、地质条件等因素出发,分析了隧道洞口段大变形的发生机理,并对围岩大变形的治理措施进行了探讨。从后期的监控量测结果来看,该隧道大变形得到很好的控制,为类似工程的处理提供参考。

| Abstract: | Mijiazhai 1# tunnel is one of the tunnels in the Xinbao Freeway with poor geology condition.Firstly, the mechanism of large deformation of early supports of Mijiazhai 1# tunnel is analyzed in this paper based on the landfomi and geology of the tunnel.Then,the treatment of large deformation of early supports is discussed.According to the result of monitoring measurement,the large deformation of early supports of Mijiazhai 1# tunnel is in the control after treatment,and the treatment provides a valuable refer... |
