scale effects on its fracture mechanism are studied in three scales of microscopic
mesoscopic and macroscopic states by rent edge tracking by triaxial rock material test system
crack line in cut plane or abrasive plane of rock specimens and breakage line of rock mass on site respectively. Method of coupling circle and square to calculate the fractal dimension is forward
whose superiorities are discussed and used to study fractal feature of rock fracture. There is a non-scale zone of 0.002—4 000 mm for studying fracture mechanism of rock in microscopic
mesoscopic and macroscopic scales. In the non-scale zone
self-similarity of distributing law of fracture structures is outer reflection of inner fracture mechanism of rock in every state. The results provide a possible method to study failure mechanism of jointed and fractured rock beyond scale limit.
