| 摘 要： | Based on the data of strain field, fault slip and acoustic emission during the deformation of some fault models, the fault interaction patterns are studied. The experiments reveal four patterns of fault interaction, i.e. static promotion or delay of earthquake, creep triggering, dynamic triggering and dynamic loading-relaxation. Promotion and delay of earthquake caused by fault interaction and mechanical property of fault combinations are preliminarily analyzed from the perspective of series and parallel connection of faults, and the relationship between patterns of fault interaction and mechanical and material properties of fault is discussed. |
