摘要:
粗糙处理后的老混凝土表面具有分形特征.通过自制粗糙度测定仪,用简单分形方法评价老混凝土表面粗糙度,并与常规测试方法进行对比.数据表明,分形维数和平均灌砂深度二者回归线性良好,可以做为混凝土的精糙度评价指标.该测量仪操作简单、使用方便,适合实际加固工程中老混凝土表面粗糙度的测量.
Abstract:
The surface of old concrete after rough treatment has fractal characteristics. Through the self-made roughness tester, the surface roughness of old concrete was evaluated by simple fractal method, and compared with conventional test methods. The data show that the fractal dimension and average sand filling depth have good linearity, which can be used as the roughness evaluation index of concrete. The measuring instrument is simple to operate and easy to use, which is suitable for measuring the surface roughness of old concrete in actual reinforcement projects.
