The composite deck pavements of highway concrete bridges in Guangdong Province have common shear diseases such as rutting,passage and so on. In order to analyze its destruction reason,in this paper,a model of tires and the composite deck pavement of concrete bridge with ANSYS combining with the climate in Guangdong has been established,the heating numerical simulation of the pavement structure respectively under the conditions of temperature and temperature-load coupling has been conducted. The results have indicated that the temperature field in inner pavement is distributed unevenly,and the weak layer of shear deformation under temperature stress is the lower AC,while the weak layer of the lateral shear deformation under coupling condition is the upper AC,and the weak layer of the longitudinal shear deformation is the lower AC. The research could provide some engineering experience with references for the structure design of the composite deck pavement in highway concrete bridge in Guangdong Province.
