摘要
对波纹型几何非光滑推土板与土壤相互作用进行了二维有限元分析，并通过表面应力、位移及土体中的应力场分析了其减粘降阻原因。为非光滑表面的减粘降阻机理的研究提供定量依据。
The 2 Dimention FE analysis of the interaction between soil and wave plate have been done and the cause of reducing adhesion and resistance were also analyzed through surface stress,displacement and stress field in soil. This study provides a quantitative foundation for the study of the mechanism of reducing adhesion and resistance of geometric unsmoothed surface.
