摘要:
为揭示冲击载荷条件下巷道围岩的动力破坏特征，采用FLAC3D建立数值模型，系统分析冲击波的传播规律以及围岩应力与能量的动态响应特征。研究结果表明：巷道顶板发生冲击时，不同方位围岩质点振动速度差异显著，最大振速分别为1.220，0.758，0.635 m/s，表明迎波侧受扰动最为剧烈，侧向次之，背波侧影响最弱。由于冲击载荷反复拉压作用下，围岩应力呈现瞬时突增特征，导致变形速率急剧提升；同时，畸变能与弹性能在弹塑性交界区发生峰值聚集并迅速释放，表明应力峰值区的能量释放是围岩破坏的主要能量来源，从而极易导致围岩扩容变形破坏。冲击过程结束后，应力峰值逐渐向深部转移，破坏范围随之增大。冲击破坏演化过程可概括为：顶板受冲击扰动→浅部围岩损伤与变形→围岩损伤区范围急剧扩展→深部围岩能量瞬时释放→巷道围岩冲击破坏。研究结果为冲击载荷作用下围岩破坏机理分析与稳定性控制提供有益参考。
Abstract:
In order to elucidate the dynamic failure characteristics of roadway surrounding rock under impact load,a numerical model was established by FLAC3D to systematically analyze the propagation law of shock wave and the dynamic response characteristics of surrounding rock stress and energy.The results show that when the roof of the roadway is impacted,the vibration velocities of surrounding rock particles in different directions are significantly different,and the maximum vibration velocities are 1.220 m/s,0.758 m/s,and 0.635 m/s,respectively.The disturbance on the wave-facing side is the most severe,followed by the side,and the influence on the back wave side is the weakest.Due to the repeated tension and compression of impact load,the stress of surrounding rock presents the characteristics of instantaneous sudden increase,resulting in a sharp increase in deformation rate.At the same time,the peak value of distortion energy and elastic energy gathers and releases rapidly in the elastic-plastic boundary area,which indicates that the energy release in the stress peak area is the main energy source of surrounding rock failure,which can easily lead to the expansion deformation and failure of surrounding rock.After the end of the impact process,the peak stress gradually shifts to the deep part,and the damage range increases.The evolution process of impact failure can be summarized as follows: roof disturbed by impact → damage and deformation of shallow surrounding rock → rapid expansion of damage zone of surrounding rock → instantaneous release of energy of deep surrounding rock → impact failure of roadway surrounding rock.The research results provide a useful reference for the failure mechanism analysis and stability control of surrounding rock under impact load.
