| 英文摘要 | To investigate the mechanical characteristics and damage mechanisms of surrounding rock mass failure caused by fault activation-induced seismicity in high-sidewall caverns, this study conducted the mesoscale low-amplitude dynamic loading modeling tests under true triaxial stress. During the tests, strain gauges, acoustic emission (AE) monitoring systems, miniature cameras, and vibration velocity acquisition system have been utilized to obtain the mechanical response, damage and failure processes, and velocity responses of the cavern surrounding rock mass. The following conclusions are obtained: (1) each dynamic disturbance triggers a high-intensity AE signal. The higher the static stress level, the stronger the AE signal caused by the same dynamic load. The first or long-interval dynamic loads can cause high-energy AE signals, potentially leading to a "mainshock-aftershock" phenomenon of stress waves within the surrounding rock mass. (2) Under the combined influence of dynamic loads applied to static loads, an increase in shear cracks is observed during the non-destabilization failure stage, yet tensile failure remains the predominant mode. In contrast, during the destabilization failure stage, shear failure becomes the dominant mechanism, indicating that shear cracks are the primary factor in the overall destabilization failure of the surrounding rock mass. (3) When investigating the properties of a seismic source using velocity waves, it is more accurate to utilize the velocity wave aligned with the direction of dynamic incidence or the combined velocity wave near the side of incident wave without significant reflection. (4) Low-amplitude dynamic loading does not alter the failure patterns induced by high static loading. The failure primarily occurs at the stress concentration points under static loading, but it tends to propagate in the direction of the dynamic loading. The research findings provide a basis for assessing the stability of surrounding rock mass in large underground caverns under the activation and seismic triggering of faults. |
