Evolution Mechanism of Deformation and Failure of Surrounding Rock during Excavation and Unloading of the High‐Stress Rock Mass [PDF]
Advances in Civil Engineering, 2020 To deeply analyze the failure evolution of surrounding rock during excavation‐induced unloading of the high‐stress rock mass, a multistage failure model was established based on revealed failure patterns. The critical conditions for wing cracks were determined. The slab crack buckling analysis was carried out. The true‐triaxial rockburst testing system
