The Research on Strain-Softening Characteristics and Local Fracture Law of Deep Granite Roadway

The complex mechanical properties of deep surrounding rocks during excavation and unloading have always been a concern in engineering communities. Based on deep roadway engineering, the mechanical properties of granite strain-softening were investigated by laboratory tests. An exponential relationsh...
