| 英文摘要 | A 3D micro-creep model based on the grain-based structure and the framework of the Particle Flow Code (PFC) approach is proposed. Simultaneously, a Voronoi polyhedral technique is employed to approximatively construct the grain structure of the real rock salt. Based on literature research, an exponential attenuation mode controlled by the temperature and stress-level is assumed to characterize variation behavior of the parallel bond diameter (PBD) with time. This model is then configured to simulate the time-dependent deformation responses associated with the damage features of rock salt. The validity and applicability of this 3D micro-creep model are verified through comparing the steady-state creep rate, multi-steps creep responses, and microcracking modes obtained in lab tests. This work could provide a promising alternative to study the micro-creep damage mechanism of rock salt. |
