In-situ observations of damage-fracture evolution in surrounding rock upon unloading in 2400-m-deep tunnels
The damage-fracture evolution of deep rock mass has obvious particularity, which is revealed in 2400-m-deep tunnels by field tests. The evolution of the excavation damaged zone depth is consistent with that of the fractured zone depth. The ratio of the excavation damaged zone depth to the excavation...
