摘要
农业机械造成的土壤压实逐渐成为一个世界性问题。运用模型的方法评价土壤压实可以有效揭示土壤压实机理。为此,分析了土壤压实模型的分类、特点和建模所需的因素,重点分析了近似分析模型和有限元模型评价土壤压实的原理和各类模型的特点,从而为有效揭示土壤压实机理提供理论依据。
Wheel traffic induced soil compaction has been a worldwide problem.Model based analysis is an useful way to uncover the mechanism of soil compaction due to agricultural machine.The paper introduced the common models used for evaluation soil compaction,including category,features and main parameters.Emphasis was put on Pseduo-analytical model and FEM model,to illustrate their unique feature and application in soil compaction,thus to provide theoretical support for soil compaction evaluation and solution.
