| 摘 要： | 在考察工程节理化岩体断裂力学特征的基础上,提出了“追踪裂纹断裂”的概念,并结合分形几何原理,建立起追踪裂纹断裂的分形模型,从分形几何的角度研究了节理化岩石的微观和宏观结构效应以及使断裂韧性提高的物理力学机制,并通过实测岩样的剪切断裂而进行了验证。

| Abstract: | In this paper,the concept of "tracing crack" is put forward on the basis of analysing the feature of fractural mechanics of the engineering joint rock.Fractal model of tracing track fracture is established by the principle of fractal geometry. Meantime, this paper studies the fractal effect of the micro-structure and macro-structure of joint rock and analyses the physical mechanism about the fracture toughness increased by the method of fractal geometry. |
