采用自编软件对蒸发过程中不同含水率广西南宁膨胀土裂隙分布的数码拍摄图像进行了二值化处理和自动化分形统计,并结合膨胀土的现场渗透试验和变形模量测试,初步建立了土体裂隙分布与含水率、渗透系数及变形模量的关系。研究结果表明,二值化像素和分形维数统计的方法均是对膨胀土裂隙的平面描述,而渗透性和变形模量的演化性状可以描述膨胀土裂隙的发育状态,并能客观反映裂隙影响下膨胀土的工程性质。
The self-made software was used to process the digitized images and the automatic fractal statistics of the fracture distribution of the expansive soil with different water contents in Guangxi Nanning during the evaporation process. Based on the field penetration test and deformation modulus test of the expansive soil, Relationship between body fracture distribution and moisture content, permeability coefficient and deformation modulus. The results show that the binarization pixel and the fractal dimension statistics are both the planar descriptions of the expansive soil fissures. The evolutionary properties of permeability and deformation modulus can describe the development state of the expansive soil fissures and can objectively reflect the influence of the fissures Engineering Properties of Expansive Soil.
