Abstract: With the diversification and refinement of numerical calculation method , more and more engineering practice problems can be solved. For the fast development of the discrete element method , the discrete element method in solving geotechnical dynamic engineering practical problems treat as the research object of the article. The historical process and the achievement of the development of the discrete element are introduced in this article. And the article attempt to introduce the position where the discrete element method in,so it may forecast the research direction.

Keywords: The discrete element method; Dynamic issue of rock and soil; Constitutive model
