Elastic‒plastic analysis of rock surrounding a circular roadway considering plastic hardening and dilatancy characteristics
Abstract Excavation of deep roadways induces plastic failure of the surrounding rock, resulting in roof caving and uncoordinated large deformation, which seriously threatens support safety and production efficiency. A four-stage stress‒strain model of the elastic zone‒plastic zone‒softening zone‒fra...
