Abstract: Surface morphology of soil in the interface between soil and solid changes while soil adhesion proceeds. The morphology is affected by some factors such as properties of soil and experimental conditions. As an important basic part of bionics research for diminishing soil adhesion, authors have studied surface morphology of stuck - soil in the adhesion interface by scanning electron microscope. Effect of normal load, moistrue content of soil, relative motion of solid surface against soil etc. On the surface morphology of stuck - soil is discussed in this paper.
