摘要
通过深入现场对隧道开挖地质跟踪观察和原有地质资料的综合分析,以地形地貌、岩层岩性及产状、地质构造、水文地质、开挖工程地质及卸荷失重现象为依据,得出隧道西出口围岩存在卸荷失重滑动位移,对隧道安全做出评价并提出了防治措施。
Through keeping tracking of the tunnel excavation and analysis of former geological date, it is concluded that the rock surrounding the west exit for the tunnel has sliding displacement due to weightlessness resulting from unloading. Thereafter, the preventative measures are advanced, following the assessment of the safety of the tunnel.
