摘要：

An this paper, in order to know how much that nonlinear factors influence the linear analysis in the road structural analysis,we attempt to find out how much the difference is between the results of the two method by numerical simulating technology, and attract the attention on this problem. We establish a finite element model for the road structure,and we use the numerical simulating program,Msc.Nastran, to analyse the response of the subgrade with considering the soil of the subgrade is a kind of nonlinear material. Then we explore the effect of the nonlinear property of the subgrade on determining the moduli of the semi-rigid subbase and base. Finally, we analyse a certain road structure with considering the nonlinear property of the subgrade only. With these analysis,some valuable conclusions are gained. They have much meaning for the road engineering.
