During the process of resisting the outer load or deformation,the cracked rock mass shows the stress hardening characteristic.
深部地下工程围岩破坏后形成较大范围的破裂岩体,在有效支护条件下具有结构效应,即具有一定的承载和抵抗变形能力,且在其承载和抵抗变形的过程中呈现应力强化的特性;同时,在破裂岩体内部存在岩块的再破坏和岩体力学性能弱化的过程;破裂岩体承载过程中应力状态及其力学特性的演化,取决于岩体整体力学性能、约束状态及初始破裂面的特征;在再承载过程中,破裂面上的主应力方向和大小均会发生变化,且破裂面上主应力方向和岩体的主应力方向并不一致,从而导致新的破裂面的形成和发展。
