摘要

Based on the theory of layered elastic systems mechanics, the stress of asphalt concrete bridge deck pavement structure systems under the action of wheel-loads is obtained and the main influence factors are considered in this paper. The numerical results of a bridge over Chongyang Reservoir is carried out by using the commercial finite element software ANSYS. The effects of various thickness and modulus of upper layer and lower layer on the mechanical indexes of pavement are analyzed. The theoretical and numerical results indicate that among the considered factors the elastic modulus of upper layer is the most important influencing the magnitude of the stress of asphalt concrete bridge deck pavement structure. The obtained results is hoped to provide the theoretical guide for the design and construction of asphalt concrete bridge deck pavement.
