Abstract

Aiming at the situation that the failure mechanism of pavement structure is difficult to be analyzed under the condition of uneven settlement of soft soil foundation, the finite element model of the mechanical response of asphalt concrete pavement is established by introducing the method of numerical analysis. Based on the analysis of four kinds of uneven settlement forms that is uniform settlement, one end settlement, both ends of settlement, and center settlement, the effects of uneven settlement of soft soil foundation on stress and strain of pavement structure under different settlement modes were studied. This provides the basis for the further study of the coordinated deformation of foundation-subgrade-pavement in soft soil area.
