Research on Bridge Deck Linear Adjustment of Large-span Continuous Rigid Frame Bridge Based on Driving Comfort
A vehicle and pavement system model was established based on MATLAB/Simulink environment.The vertical weighted acceleration root mean square of the vehicle seat is used as the evaluation index of driving comfort.The relationship between the presetting-height of 3L/8 side span,the presetting-height of mid-span position and the thickness of concrete pavement layer at the top of side pier and the vertical weighted acceleration root mean square of vehicle seat was analyzed.According to the analysis results,some measures are put forward to improve the bridge deck linear smoothness by adjusting the presetting-height of 3L/8 side span,the presetting-height of mid-span position and the thickness of concrete pavement layer(leveling layer)at the top of side pier,which can improve driving comfort.In the stage of bridge deck pavement,the pavement linear should be fitted according to the original preset bridge linear,while taking into account the driving comfort.
