摘要
Abstract
Without interrupting traffic, the bridge vibration generated by driving shocks has significant ef⁃fects on the quality of bridge deck pavement repair. Therefore it is necessary to study and adopt reason⁃able support measures to control the vibration. Based on the plane finite element model, this article makes a vehicle-bridge coupled analysis of dynamic traffic flow to find the status of bridge under the vehicle loads when the bridge is under half load and half construction condition. It also compares and calculates the internal force time curve and the deflection time curve in two different state of structure control sec⁃tion in reinforcement. Finally, the article checks the bridge safety and reasonable support measures ac⁃cording to the analysis results, in order to provide reference for relevant construction.关键词
