摘要

应用剪切梁理论,研究了在定常侧压力和周期性的反平面剪切载荷共同作用下,岩层层间界面载荷突变及能量释放特性由于宏观裂纹前方损伤过程区的存在,当卸载过程不能覆盖加载过程造成的损伤区时,会产生 “应力锁死”现象。而当后续再加载过程区的前锋与“应力锁死区”相接时,会产生载荷突变,从而导致冲击载荷的发生。
With the shear beam model, it is investigated the source of shocking load and its energy release related properties. Because of the existence of the damage process zone ahead of the macro crack, stress-locking would occur if the unloading process can not erase the loading damage-process zone. And if the reloading front of damage process zone is being connected with the area of stress locking, the shocking load will happen.
