    Numerical analysis of deformation and failure characteristics of deep roadway surrounding rock under static-dynamic coupling stress

    In actual production, deep coal mine roadways are often under typical static-dynamic coupling stress (SDCS) conditions with high ground stress and strong dynamic disturbances. With the increasing number of dis...

    Tunnel failure in hard rock with multiple weak planes due to excavation unloading of in-situ stress

    Natural geological structures in rock (e.g., joints, weakness planes, defects) play a vital role in the stability of tunnels and underground operations during construction. We investigated the failure characte...

    Perturbation effect of rock rheology under uniaxial compression

    Soft and medium-hard rocks are subjected to high rheology under high stress, and they are prone to a relatively large-degree of deformation when perturbed by external impacting loads. The phenomenon where rock...
