Vehicle Load Function And Its Adverse Impact Analysis Of Reinfoced Concrete Bridge

In this paper, we analyse the reinforced concrete bridge in the car under load and the power to respond to the adverse effects of vibration to the environment through a practical engineering, completely record the experimental load structure under the bridge and reflected status of the structure, set up the structure of the bridge modelthrough finite element analysis software. Analise power characteristics of the ideal structure through additional incentives.Contrast drawn vehicle traffic on the surrounding structure of the impact of noise and vibration through the testdata, as well as finite element analysis of the model. Analyse the speed of vibration of the bridge through the bridge at a different speed, as well as consider the role of road under the power formation response. When Bridge is under different speeds of the car passed, impact coefficient curve at high speed and low speed motor vehicles are peak, the overall is upward trend. Pavement factor affect the impact of the bridge, the road less formation, the impact factor of the bridge is larger. According to examples around the country related to the environment and norms, Divid motor vehicle traffic in the affected areas of the building structure andn affect people to the threshold. Give an advice of reducing environmental noise of the adverse effects of the structure。The results show that the impact load on the bridge has great influence. By improving the flatness of the bridge to limit the speed and the draw with, such as isolation can reduce the vibration impact. The results of the analysis of the vibration of the widespread impact give great significance in guiding.
