马鞍山隧道地表孤石震动监测研究

Research on vibrative inspection of surface solitary stone in Ma'anshan tunnel

针对马鞍山隧道地表山顶一巨型孤石在隧道爆破开挖的扰动下的稳定性,进行了监测及稳定性评价,给出孤石稳定的评价标准及结论,对目前隧道开挖过程中爆破震动对地表危险性构筑物的震动影响提供参考。

The paper undetakes the supervision and stability evaluation on the stability of the huge surface solitary stone on the top of Ma＇anshan tunnel in the interruption of tunnel blasting evacuation,provides the evaluation standards for the solitary stone＇s stability and its conclusion,and provides the direction for the vibration influence of the blasting vibration on dangerous buildings on the surface.
