应用分形几何研究钢筋混凝土结构裂缝扩展形式,表明结构表面裂缝的分形维数与结构力学性能之间存在良好的线性相关性;为了准确测定分形维数,结合工程实例对比分析了盒计数法和数字图像盒维数法测得的分维值,并讨论各自的优缺点及各自测定的条件,结论对分维值的准确测定起到一定的指导作用。
Fractal geometry is applied to study the crack propagation in reinforced concrete structures. It shows that there is a good linear correlation between the fractal dimension of structural cracks and structural mechanics performance. In order to accurately determine the fractal dimension, the box counting method and numerical method The fractal dimension value measured by the image box dimension method, and discusses the advantages and disadvantages of each and the conditions of their respective determination. The conclusion can guide the accurate determination of the fractal dimension value.
