Soft rock wall of tunnels in deep mining will have large creepdeformation when the stress in rock is near its ultimate strength.
在深井软岩条件下，巷道围岩应力状态处于岩石强度极限邻域内，围岩会产生较大的蠕变变形。
2
Meantime, the creep stability criteria of rock sample, analytic expressions of the creepdeformation, the creep speed and the creep acceleration are given.
同时，得出岩石试件蠕变稳定性的判别准则和蠕变变形、蠕变速率和蠕变加速度的解析表达式。
