Study on Soil Adhesion Phenomena by Chemical Adsorption

In this paper, by the adhesion theory of chemical adsorption, the soil adhesion phenomena of normal adhesion, horizontal adhesion and non water adhesion were analyzed. The factors affecting adhesion force such as normal pressure,temperature, pressing time were analyzed. The model can well explain the adhesion phenomena including some that can not be explained by existing theory, such as relationship between adhesion force and soil texture, ion exchange, pH value. The effective way of reducing adhesion-non smooth surface bionic shape changing, eletroo smosis and surfacemodification of soil touching.
