Abstract
In this paper, using fractal theory, the geometric structure of real soil was described with its section view and section particle area fractal dimension d of porous media was counted. The volumetric solid content and the relation between volumetric solid content and porous media particle arrangements as well as measure scale were obtainted. A heat conduction model was established and the effective thermal conductivity of real soil based on the volumetric solid content was calculated.
