Abstract
In order to provide the reasonable optimization measures for the construction of long-span steel bridge deck pavement in the alpine area, the actual pavement effect under the real load is studied by simulation simulation with the finite element analysis software relying on the construction of the bridge deck of No.1 Bridge of Haidong Avenue, Ledu District, Haidong city. Through different load positions and loading methods, the control load loading points are determined, and the parameterized analysis is carried out for the elastic modulus, thickness and temperature difference of the pavement, and finally the structural parameters of the pavement suitable for the bridge are obtained; the experimental analysis results show that the theoretical calculation idea adopted is feasible, and the measured value is within the expected range. It can be seen that the construction optimization measures and suggestions are of great significance to the construction of steel bridge deck pavement in the high cold area.
