Time-delayed strain rockburst (TDSR) refers to a time-delayed rockburst in rock mass without structural planes in the rockburst zone and its development mechanism is still unclear. Here, the TDSR occurrence, geology, stress environment, excavation and support characteristics of deep granite tunnels ...
In this research, the combination of theoretical approach and numerical simulation was employed to comprehensively understand the initiation mechanism of time-delayed rockburst and analyze the time-delayed failure laws for surrounding rock after excavation unloading without prompt support. The investigations ...
