| Abstract: | This paper introduced briefly a method to analyze the mass fractal dimension Dm of pore structure in soil by using the binary images of soil sections, and studied Dm of four types of soils as well as the factors influencing Dm . The results showed the potential of Dm to describe quantitatively the spatial distribution characteristics of pore structure. Generally, Dm increased with the increases of pore area, while decreased with the increase of large pores and soil depth. However,the soils with fine texture generally had a smaller Dm compared with the soil having coarse texture. |
