STUDY ON THE CO-RELATION LAW OF FRACTAL DISTRIBUTION OF CRACK IN ROCK STRATUM
岩层裂缝分形分布相关规律研究

The statistical research results of fractal distribution of crack in rock stratum is introduced. The rock samples are taken from the rock cores of length about 1000 m of three geological drilling holes. Under the condition of identical geological mass, a co-relation law is found between fractal dimension of fissure and production of strength and elastic modulus in different rock strata. The physical mechanism of rock deformation and split affected by ground stress is discussed.
