基于分形理论的钢筋混凝土梁式桥裂缝发育特征

Developing nature of cracks in reinforced concrete beam bridge with fractal theory

采用分形理论分析了钢筋混凝土梁式桥裂缝的分布特征。实例计算表明:裂缝分布分维数可很好地表征裂缝的发育程度;桥梁主梁裂缝的分维数可以作为衡量结构老化程度的重要指标。

based on fractal theory, the distribution feature of cracks in reinforced concrete beam bridge was analyzed. A case study indicated that the fractal dimensionaity can depict the developing nature of cracks, it is a good tool to examine structural operation.
