Dynamics Simulation Analysis on Composite Bridge Deck Pavement Structure

LI Ming-guo,LIANG Dong-ping,NIU Xiao-xia,LU Chang-he(Guangdong Hualu Transport Technology Co.,Ltd.,Guangzhou 510420)  
This paper,taking asphalt concrete bridge deck pavement of expressway concrete beam bridge as the study object,on the basis of elastic mechanics,with the finite element software LSDYNA,has established structure model for asphalt concrete bridge deck pavement of concrete beam bridge,to study the stress sensitivity of asphalt concrete bridge deck pavement structure of concrete beam bridge under different conditions as different vehicle speed,automobile braking and road longitudinal gradient,which could provide references for composite bridge deck pavement structure design.
