Abstract

In order to study the influence of weak dynamic disturbance on rockburst, test on cubic medium-coarse grained granite specimen with a circle hole was conducted to simulate the rockburst ejection process in circle tunnel subjected to weak dynamic disturbance. Three loading paths, namely, no disturbance, weak dynamic disturbance starting at high-stress level, and weak dynamic disturbance beginning at a low-stress level were considered. The testing process was recorded using AE and video monitoring system. The ejection failure process, characteristics of rockburst pit, acoustic emission signal characteristics and rockburst intensity were investigated. The testing results show that the weak dynamic disturbance can reduce the stress level at the occurrence of rockburst and increase the range of rockburst. The applied dynamic disturbance at a high-stress level leads to a rapid occurrence of rockburst. In contrast, when the weak dynamic disturbance is applied at a low-stress level, rockburst will occur in a gradual manner. In addition, compared with that without dynamic disturbance, rockburst with the weak dynamic disturbance starting at high-stress level has a higher intensity, while that with weak dynamic disturbance starting at low high-stress level has a lower intensity. This is because that weak dynamic disturbance starting at high-stress level is capable of stimulating and amplifying the energy release process, while weak dynamic disturbance starting at a low-stress level is only capable of stimulating the energy release process.
