1) stress hardening
应力强化
1.
Using RFPA to study on mechanical characteristics of cracked rock mass reinforced by bolting and grouting, it is obtained that the stress hardening characteristics of the cracked rock mass in uniaxial compression tests were validated, and the evolutive process of cracking and deformation of the rock mass reinforced by bolting and grouting was reflected.
验证了注浆加锚岩体在承载过程中具有应力强化特性;反映了注浆加锚岩体破裂和变形的发展过程;揭示了锚杆对岩体提供应力和位移约束机理。
2.
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。
