摘　　要：采用分形理论分析了混凝土裂缝的分布特征,实例计算表明,裂缝的分布具有分形的统计自相似性.其分布分维数能很好地表征裂缝的发育程度,且它与结构老化的其它指标能相互印证;因此,裂缝分布分维数可以作为衡量结构老化程度的一个有效指标.Analyzed characteristics of the concrete crack through fractal theories ,an example expresses that there are some likenesses between crack distributes and fractal covariancc; It and aging other index sign in construction can corroborate with each other;Therefore, to divide the dimension number of crack distributes can be used as a valid index sign that measures the aging degree in construction.
