Abstract :
The macroscopic fracture s of rock are strongly linked to the presence of microstructures and micro-defects within. And the evidence of deformation is left after fracture process. This paper put the sericite phyllite and siliceous plate phyllite of Middle Devonian series as the research object on upriver of Jinsha River. The micro-rupture properties of rock are judged and the relation between the form and mechanism of phyllite micro-rupture and mineral component is revealed through scanning electronic microscope and mechanical tests. We analyze the physical meaning of rock fracture combined with mechanic characteristics of macroscopic fracture. So we acquire the evidence of the establishment of bridge between rock micro-rupture mechanism and macroscopic fracture analysis.
