Study on Energy Release of Surrounding Rock under the Multiple Unloading Disturbance during Tunnel Excavation

During excavation of deep rock, the release of strain energy plays an important role in geologic hazards caused by excavation. However, in the previous studies, the influence of transient unloading of in situ stress caused by blasting excavation has been ignored, and the blasting excavation of a tun...
