| Abstract: | According to the traffic load characteristics,the numerical simulation was carried out using the finite element software ABAQUS to simplify the subgrade under traffic load to a 3D model.The dynamic parameters of traffic load,s including static load,moving constant load and sinusoidal load,were simulated and analyzed by adopting pseudo static method.By using the existing constitutive relation of elasto-plastic soil,the finite element model of subgrade soil was established.By determining the parameters of mod... |
