Non-uniform failure mechanism and stability control of mining roadway under deviatoric stress field
Abstract Based on the elastic–plastic theory, the analytical formula of the second invariant J 2 of deviatoric stress at any point around the circular roadway under the non-uniform stress field is derived. The distribution law of J 2 of surrounding rock under the three-dimensional non-isobaric stres...
