| 英文摘要 | The triaxial shear test method with consolidation, low temperature freezing, and radial unloading was applied to simulate the mechanics process of the unloading process of deep artificial frozen clay during the excavation of a freezing mine shaft. The triaxial unloading creep test on artificial frozen clay showed that the first and second stages of the creep deformation occur only when the deviatoric stress is low and that creep deformation accounts for > 70% of the total deformation. The third stage of creep deformation occurs only when the stress level exceeds a certain critical value, and is characterized by the frozen soil undergoing a large plastic flow, with breaking for 3 to 5 h. The creep strength envelope at low confining pressure is linear, in compliance with the Mohr-Coulomb strength criterion, and the critical stress value in the third stage can be described with the improved Zienkiewicz-Pande parabolic yield criterion. |
