| 摘 要： | 简述了离散单元法的发展现状，介绍了目前离散单元法的应用情况，分析了离散单元法在土壤行为中应用的可行性，指出离散单元法应用于土壤这样的多相不连续复合体系中，以离散单元的总体行为来描述土壤动态行为具有独特的优越性，提出了在离散单元法前提下建立土壤力学接触模型的方法。

| Abstract: | The developmental status and the application of distinct element method(DEM) were introduced in brief.The feasibility of applying DEM to describe soil dynamic property was analyzed.The special priority of using the whole theory of DEM to describe soil dynamic behavior in the discontinuous multiphase multiple systems such as soil was pointed out.The method to establish the soil model based on DEM was put forward. |
