动力模型试验已经广泛应用于土与结构相互作用的研究中，其中模型土的配制尤为重要。根据所选土样的基本物理力学性质，制作了不同干密度、含水率的环刀试样，通过直接剪切试验，得到了不同试样的初始剪切模量。在试验的基础上，探讨了初始剪切模量与试样干密度、含水率之间的关系。基于动力模型试验的相似关系得到了模型土配制的基本要求，结合探讨结果分析了不添加其他材料的模型土配制，得到定性的模型土配制方法，结果可为以后类似试验的模型土配制提供参考。

Dynamic motel test has been widely applied to the study of soil-structure interaction,in which the preparation of model soil matters the most.This paper prepares samples with foil sampler of different dry densities and water contents according to the soil physical properties,and then subjects the samples to direct shear test to get the original shear modulus.Considering the results,the correlation between the original shear modulus and the soil dry density and water content is analyzed.The request of the preparation of model soil is obtained on the basis of similitude law in dynamic model test.The preparation of model soil without other materials is analyzed through with above findings.Then a qualitative way of the preparation of model soil is obtained.It can provide useful and helpful directions for the preparation of model soil in similar test.
