摘　　要：由于土具有复杂的弹性及塑性 ,仅从宏观上分析和试验 ,往往难以建立一个令人满意的、具有普遍性的本构模型 ;假如从微观分析 ,则可把土颗粒看作一个单纯的弹性体来分析 ,其结果应是较准确的 .讨论了土的组成及土颗粒的受力情况 ,从微观角度对库伦公式进行了分析 .将土样分组 ,分别测得各组参数 ,以描绘土样性质 。Because of the complex double properties of soil’s elasticity and plasticity,it is difficult to establish a satisfatory universal constitutive model from macrocosmic analysis and tests.It is easier to analyze if looking on soil particles as elastic objects,their analysis is more accurate.In this paper, the analysis of the composition of the soil and stresses of soil’s particles is discussed.Coulomb equation is analyzed from microcosmic aspect.Soil sample is dividedinto several groups and their parameters are used to describe the property of the soil,they are closer to microcosm.
