摘要：The research of load-sinkage characteristic between soil and vehicle is focused by many scholars in vehicle terramechanics field all the time. The classical models of load-sinkage characteristic between soil and loading plate were established based on a large amount of in-situ tests, but it's sometimes difficult to conduct the in-situ experiments. So the finite element method was used to analyze the load-sinkage characteristic relationship between soil and loading plate based on the triaxial compression experiment date. The finite element calculation result shows that the simulation load-sinkage curve is very close to the curve fitted by classical model. According to the simulation date, a new model, double-exponential equation, to describe the load-sinkage characteristic of soil was proposed, and the R2 ≥ 0.99. The new model was verified by fitting the measured date of wet clay and have a better accuracy compared with other models which is bekker, LSA and Kacigin-Guskeo model.
