Study On Stress Behaviors Of Deck Pavement Of Highway Bridge Based On ANSYS

Bridge deck parts of the bridge is easily to occur early-disease.At present in our country, the existing design specification of bridge and road does not stipulate design requirements and designparameter.The method of design can not prevent occurrence of early-disease.In this paper, Anhui Highway structure of bridge deck as background. By ANSYS finite element to establish a model of bridge deck. Stress analysis carried out for the bridge deck.The structure of bridge deck are simplified and established an effective theoretical model of bridge deck. Analysis of the most unfavorable position for the bridge mechanical.Simulated the vehicle load in the unfavorable position,Analysis of the force characteristics of bridge deck.According to the current situation,In view of the axle load changes analyzed the mechanical characteristic. Obtained the structure of bridge deck mechanical characteristic.According to the characteristics and make recommendations on this status. Such as changing the pavement structure layer thickness, improving asphalt concrete modulus. Analysis the feasibility of the measures, and the increase of the thickness of the simulated data can only play a part of the improvement. The increase of the modulus can improve the stress.
