摘要
应用分形（ｆｒａｃｔａｌ）理论研究混凝土结构几何损伤形态，分析了分维解析的适用条件，对混凝土结构损伤开裂形态、裂缝覆盖率、总延长和分歧延伸作了定量化解析；讨论了分形特征值和混凝土强度、裂缝宽度的关系；
The authors study geometry aspects of damage in concrete structures by fractal geometry theory. The application conditions of fractal dimension analysis are discussed. The appearance damage, crack ratio, total extension and diverge elongation of cracking are quantified. The relationships between fractal characteristic values, strength and width of crack are investigated. This study introduces a new quantitative analysis means for evaluating geometry aspects of damage and durability of concrete structures.
