Analysis on the Application of Expressway Bridge Widening Construction Technology
The traffic pressure on expressways continues to increase with the increase of vehicle traffic flow,and the weakening of traffic operation organization ability of highway bridges seriously restricts the function of the highway.The bridge widening reconstruction engineering can not only effectively reduce construction cost,reduce traffic space,but also improve the traffic service and prolong the service life of the bridge.The splicing and widening construction technology of new and old bridges is the key content of bridge widening,which directly affects the stability and safety of bridge structure operation.Based on the construction technology application research of an expressway box girder bridge widening project,this paper focuses on the specific analysis of the splicing structure and construction technology of new and old bridges,so as to provide reference for similar engineering construction.
