Abstract EN
Disasters of deep underground caverns often occur during excavation or operation stage, which is closely related to the growth and evolution of surrounding rock cracks.
The understanding of spatial distribution of internal cracks in rock mass is the key to reveal its deformation and failure mechanism.
The transparent resin material with prefabricated crack was used to simulate the initial crack inside the rock, and the uniaxial compression experiment of transparent rock material under complete stress-strain path was carried out by using the rock mechanical rigidity testing machine.
Four high-speed cameras were arranged around it to record the images of the same moment from different angles.
Based on the theory of stereoscopic vision, a calculation method for the three-dimensional constitutive structure of crack propagation inside the rock was proposed, which can quantitatively describe the crack spatial morphological change.
Therefore, the calculation method provides a reliable theoretical support for the surrounding rock reinforcement of underground engineering.
