摘要
对高掺量钢纤维混凝土 (SIFCON)在不同纤维掺量 (体积分数 )下的力学性能及破坏形式进行了数字图像分析 ,并用分数维对SIFCON的表面裂缝进行了定量描述 .结果发现 :不同纤维掺量下的SIFCON表面裂缝存在分形特征 ,分数维可以对表面裂缝进行定量描述 ,SIFCON的力学性能与分数维之间存在较好的关系 .
The mechanical properties and digital image analysis of slurry-infiltrated fiber concrete (SIFCON) were investigated experimentally. Fractal dimension was used as a parameter to characterize the cracking pattern on the surface of SIFCON. It was found that there were fractal phenomena for different fiber content of SIFCON. The results indicate that fractal dimension can be a parameter to characterize the cracking pattern on the surface of SIFCON quantitatively, and there exists a good correlation between mechanical properties and fractal dimension.
