| 摘 要： | 随着隧道开挖掌子面的推进,将会引起围岩应力的释放,届时岩体的应力将会进行重新分布,甚而当此应力重分布达到某一极限超越围岩强度等级,将产生严重的后果。此时围岩的位移也会变化,尤其顶部位移更需考虑,现在主要考虑应力释放率对围岩位移的影响。

| Abstract: | With the advance of working face tunnel excavation,rock will cause the release of stress,the stress will be re-rock distribution,even when the stress redistribution reaches a certain limit beyond the rock strength rating,will have serious consequences.At this point the displacement of rock will change,especially at the top of the displacement need more consider,now consider the effects of stress release rate on the main rock displacement. |
