摘要
影响隧道围岩稳定性的因素中断层首当其冲。以其不同的力学机制 ,文中将断层影响区域分为三大类 :张拉型正断层发育带、扭剪性断层区域及压性逆断层区域 ,得出不同断层区域对隧道开挖的影响机制及地质灾害的防治对策。
Fault is the prime factor that impacts the stability of wallrock of tunnul.According to the mechanics character,fault is divided into three groups,which are tension noemal fault,torsion shear fault and pressure reversed fault.The mechanics theory of tunnel wallrock in three faults and the method of controlling geology disaster are achieved.The result is applied in predicting and decreading disaster engineering,improving the spreed of constructing tunnel.
