Numerical simulation of double deck pavement for long-span cable-stayed bridge

Abstract

The double-deck pavement of the long-span cable-stayed bridge was set as the research object, by setting the load position, load condition and reference point on the bridge deck, the parametric analysis of the elastic modulus, thickness and temperature of the pavement material was performed. Then Pavement structure parameters suitable for the bridge were get. The finite element software was used to simulate the pavement effect of the No. 1 bridge of Haidong Avenue under the actual load, which provided reasonable optimization measures for the construction method of large-span steel bridge deck pavement in high and cold areas.

Analysis of Mechanical Response of Epoxy Asphalt-Repaired Pavement in Pothole Interface on Steel Bridge Deck under Coupled Temperature-Dynamic Loading

“…Most secondary damage occurs at the interface between the pothole and the original pavement layer. If the repair interface isn't adequately bonded, the combined effect of temperature-load coupling [9] can weaken the integrity between the pothole repair block and the original pavement, resulting in shear and tensile fatigue damage [10,11].…”
