摘    要:岩土介质是晶粒状材料,存在大量的孔隙。这些孔隙的存在严重地影响岩土介质的力学、物理和化学性能。大量的研究表明,岩土介质的孔隙几何从原子尺度到晶粒尺寸范围内均表现出分形特征。目前分形几何已被广泛应用来研究岩土的孔隙率,输运特性和渗透性等等。本文从5个方面来讨论岩土介质的分形孔隙和分形粒子:①分形几何简介;②孔隙介质的分形模型;③岩土介质的分形孔隙特性和它们的分形量测方法;④岩土的分形粒子;⑤水土保持估计中的分形毛细管模型。

关 键 词:岩土介质  分形  孔隙  粒子  水土保持

Abstract:Rock and soil materials consist of grains and pores. They arc natural porous media. The presence of pores strongly a#ects mechanical, physical and chemical properties of the rock and soil materials. Research results indicate that the pore geometry of the rock and soil shows the fractal behavior over the range from atom scale to grain size. So far, fractal geometry has been widely applied to study the porosity, permeability and percolation properties of the rock and soil, and other materials. In this paper, ...
Keywords:rock and soil materials  fractal  pores  particles  soil water retention
