Abstract

Abstract: In order to predict the static mechanical performance of flexible pavement laid on swampy ground under vehicle load, Duncan-Chang constitutive model is selected to simulate the nonlinear elastic properties of ground soil. The flexible pavement is simplified as a mechanical model of membrane-beam element, and the large deformation and contact nonlinearity of flexible pavement are also consisted. A nonlinear analysis model of flexible pavement structure is established by using the finite element analysis software ABAQUS, and the deformation and internal force response of the flexible pavement under load are obtained. The numerical analysis result is verified with the load test result. The result shows that the nonlinear analysis method of flexible pavement structure based on Duncan-Chang constitutive model can meet the requirements of engineering analysis. Key
