摘　　要：详细介绍了三个地质钻孔共计１０００余米岩芯的裂缝分布分形统计研究结果，揭示出了同一地质体中，不同岩层裂隙分布的分形维数与岩层岩样强度模量积呈幂函数的相关规律，并从构造应力场作用使岩石变形破裂的角度给出了明确的物理解释。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.
