为了更深入地考察淤泥的分形特性以及固化处理对淤泥分形特性的影响,以武汉市官桥湖淤泥为例,在分析淤泥扫描电镜图像的基础上,采用Matlab编程研究淤泥单元体的多重分形特性,并探讨水泥和粉煤灰固化对淤泥多重分形特性的影响,考察了多重分形参数与淤泥强度特性之间的关系.结果表明:淤泥单元体在一定像素尺度范围内具有多重分形特性,多重分形谱呈不对称的左钩状;多重分形谱能反映单元体的分布特征,固化处理使淤泥单元体结构分布均匀;容量维、信息维、关联维、多重分形谱宽和非对称系数与无侧限抗压强度关系密切,可用多重分形参数反映强度变化的规律.
In order to further investigate the fractal characteristics of silt and the effect of curing treatment on the fractal characteristics of silt, taking the Guanqiao Lake silt in Wuhan as an example, based on the analysis of silt scanning electron microscope images, the multifractal characteristics of silt units were studied by Matlab programming , And discussed the effect of cement and fly ash solidification on the multifractal characteristics of silt, and investigated the relationship between multifractal parameters and silt strength characteristics.The results show that the silt unit has multifractal characteristics within a certain pixel scale, and the multifractal The fractal spectrum can reflect the distribution characteristics of the unit body. The solidification treatment makes the unit structure of the sludge unit uniform. The capacity dimension, the information dimension, the correlation dimension, the multifractal spectrum width and the asymmetry coefficient are the same as those of the unmarked Compressive strength is closely related to the limit, the available multifractal parameters reflect the law of intensity changes.
