| 摘 要： | 土是由土的颗粒组成,存在着大量的孔隙.研究表明,土体中的颗粒和孔隙表现出分形特征.本文从两个方面介绍了土体物理性质的分形研究:(1)分形用于定量描述土体的的密度,孔隙表面积等物理参数;(2)分形用于定量描述土体的构形,如土体微观结构,孔隙尺寸分布,颗粒尺寸分布等物理性质.

| Abstract: | Soil mass consists of particles,in which there exists numerous pores.Research results show that the particles and pores in soil express fractal behavior.This paper reviews the applications of fractals in research of physical properties of soil:(1)fractals have been used to describe physical parameters of soil such as density and specific surface area;(2)fractals have been applied to quantitatively describe spatial variability of soil which includes soil microtopography,particle-size distribution,pore-size distribution. |

| Keywords: | soil mass physical parameters spatial variability fractal fractal dimension |
