| 英文摘要 | Upon conducting simulated fault friction tests on granite specimens under various normal stresses utilizing CNL and CNS rock joint shear testers (RJST-616), we aimed to comparatively analyze the stick-slip behavior characteristics during fault sliding. Our results reveal that the sliding behavior of granite simulated faults under different normal stresses is primarily marked by stick-slip features. Both the static shear stress drop and the stick-slip time interval exhibit an exponential growth relationship with the normal stress, whereas the spatial frequency of stick-slip events demonstrates a negative correlation with the normal stress. Furthermore, we observed an exponential growth relationship between the critical slip weakening displacement and normal stress, with the growth rate showing a rapid and then slow trajectory. Additionally, we established an intrinsic connection between different seismic source parameters using normal stress as a bridge. Finally, we unveiled the occurrence and recovery mechanisms of fault stick-slip under varying normal stresses from the perspective of the friction cone. These findings not only enhance our understanding of the behavioral characteristics of fault stick-slip but also provide novel insights into the seismic evolution of natural fault systems. |
