有效应力下多孔介质微观结构的分形特征
Fractal feature of microstructure of porous media under effective stress
摘要
Abstract
Based on the fractal geometry theory, this paper establishes a fractal calculation model of effective stress, analyzes and discusses the relationship between microstructure of porous media and effective stress, reveals the influence law of the effective stress on the microstructure of porous media. The results of the study show that the fractal calculation model of effective stress can describe the relationship between the effective stress and the microstructure of porous media. With the increase of effective stress, the fractal dimension of the porous media increases exponentially, the porosity and pore number in the porous media decrease exponentially and the mean radius of pores decreases.关键词
