In order to obtain the rule of creep failure of high ground stress rock
the process of creep failure of surrounding rocks is simulated under the action of high ground stress at different depths in deep engineering
then time-creep
horizontal ground stress (depth)-creep curves and time-horizontal ground stress (depth)-creep curved surface are obtained. According to the rules of Mohr-Coulomb and Griffith
the theory of nonlinear creep is proved. And a new idea is offered
which predicts the deformation of tunnel wall rocks surrounding in deep engineering The non-linear rheology theory proposed by Zheng Rongming and Sun Jun is verified through calculotions.
