Highway bridges are the critical infrastructure of the nation.It play an important role in the social and economic development.In service process,highway bridges may suffer from the effect of natural and traffic environment.With the gradual aging of components,the bridges with various defects are increasing year by year.The bridge structure generally consist of the superstructure and the substructure,wherein the superstructure is the main load-bearing structure of the bridge.In China,concrete bridges account for more than 95% of the total number of bridges.Therefore,detecting and analyzing superstructure defects of concrete bridges is quite necessary.
