偏压滑坡地段围岩受力特征测试分析

Measurement and analysis of stress conditions of tunnel's surrounding rock masses at deviation pressured landslide section

通过对担架哨隧道偏压滑坡地段监测数据的分析,得到了工字钢和锚杆等支护构件的受力状况与围岩地质状况之间的必然联系,并表明可以通过埋设测试元件来了解围岩的地质状况,合理设计隧道的支护措施。

By analyzing the measurement data for Danjiashao Tunnel at unbalance pressure landslide section, the relationship between the bending moment of H-steel , the stress of the surrounding rock masses and the geological condition is obtained; which means that the surrounding rock masses stability can be forecasted by setting measurement apparatus so as to design the tunnel抯 supporting measures reasonably.
