摘要：

<正>The irregular and rough profile of fracture surfaces of rock can be regarded as havingself-similarity statistically. The authors apply a new geometry----fractal geometry to describe thisirregularity. Fractal models of the transgranular fracture and the combined intergranular andtransgranular fracture are established. The fractal character of fracture surface of rock is examined byelectron scanning and optical fractographic analyses. Finally, the relation between fractal dimensionand macromechanics quantities of rock fracture is obtained.
