The micro cracks of concrete that formed during the injury evolution have obvious self-similarity features, which are known as fractal features. 摘要混凝土在损伤演化期间所形成的微裂纹具有明显的自相似特征，即分形特征。
The linking process form microcracks to a fatal macroscopic crack is dominated by the strong interaction among neighboring microcracks. 微裂纹串接为宏观灾难性裂纹的过程取决于相邻微裂纹的强相互作用。
