摘要
通过在乌鞘岭特长隧道 7号周期性活动断层内施工的经过 ,简要分析强挤压高应力软弱围岩条件下周期性活动断层内隧道施工支护的变形规律和结构内力的变化特点 ,介绍此类围岩条件下隧道施工的基本方法和要求 ,并对施工中应注意的事项提出建议措施。
A description was given of tunneling in a cyclical a ctive fault for Wushaoling Super Long Tunnel. An analysis was made of laws of de formation of tunnel support, and changes of internal force in this tunnel. An i ntroduction is given to basic tunneling method and requirement for such geologic al condition.
