基于分形渗流模型的导电沥青混凝土的分维计算
Estimation of fractal dimensions of conductive asphalt concrete based on fractal and percolation model
摘要
Abstract
This paper introduces the fractal theory to the study on the distribution characteristics of the conduc-tive paths of asphalt concrete by using fractal dimension to describe the conversion process when asphalt concrete are changed into conductor.Based on Matlab,the images information of the box -counting dimension combined with the conventional image processing method is obtained.The relationship between fractal dimension and vol-ume content of the conductive material was also analyzed.The results show that:the conductive path of asphalt concrete has obviously statistical significant similarity on fractal,and fractal dimension increases by the graphite content at two -dimensional plane.In addition,the change trend of fractal dimension is similar to the depend-ence of resistivity and graphite content.The results indicate that fractal dimension can describe the degree of connectivity clearly and quantitatively when conductive asphalt concrete forming a percolation path.关键词
