摘要
以车辆行驶的表层沙土为研究对象，用土壤动态三轴仪对车辆行驶的表层沙土的力学特性进行了试验研究，建立了适于车辆行驶的表层沙土的非线性弹性邓肯（Ｄｕｎｃａｎ）本构模型。研究结果表明它能够较好地反映车辆行驶的表层沙土的本构关系。
The mechanical properties of top sand under moving vehicle are studied by soil dynamic triaxial test apparatus. The nonlinear elastic Duncan constitutive model of top sand under vehicle is established. Analysis shows that the model can well describe the interaction between vehicle walking machine and top sand, and can be applied to analyse their mechanical performance and develope vehicle sand.
