STUDY ON FRACTAL MECHANISM OF FRACTURES IN JOINT ROCK MASS

Yang Tihua(Tong ji University,Shanghai 200092)  
This paper established tracing craking fractal model by cormbining with the principle of fracture mechanics of rock mass and based on analyzing the fracture mechanics feactures of rock mass,probed into the fractal effect of the fracture toughness of discontinuous rock mass, nd Verified the model through press-shear test.
