Study on maintenance time based on deterioration prediction model of main girder
Abstract
With the increasing number of bridges in Shanxi Province, the difficulty and complexity of bridge maintenance and management tasks have increased significantly. In this paper, based on the existing prediction model, combined with the characteristics of local heavy traffic and large temperature difference environment, the prediction model of concrete carbonation, girder cracking, prestress loss and concrete shrinkage and creep is established. According to the linear law of deterioration curve, the best maintenance time of girder suitable for local characteristics is determined, which can provide guidance for later maintenance management of bridge.
