Abstract:
The temperature field and thermal deformation of steel bridge deck during gussasphalt pavement paving are studied by the numerical simulation technology. A temperature field model of steel box girder is established to analyze the temperature distribution law of steel bridge deck during gussasphalt pavement paving, and the worst temperature load equation is fitted subsequently. The temperature load equation considering the construction process is established based on the time-space equivalence principle. The local thermal deformation of the steel bridge deck is calculated, and the effect of thermal deformation on the pavement is discussed. Research results show that the paving temperature has a great effect on the steel bridge deck. After 10min of paving, the local temperature of steel bridge deck reaches 120℃, and reaches a maximum of 123℃ after 17min. Local temperature deformation appears in the steel bridge deck plate, and the maximum vertical displacement is 7.5mm. This can lead to the thickness discrepancy of pavement, with a simulation value close to 1mm.
