Study on the Adaptability of Vehicle Loads in Special Lanes for Trucks on Highway Bridges

To study the adaptation of current automobile design load highway bridges in China case separation passenger cars and trucks, a statistical method is proposed this paper to data special lanes for trucks. Four typical truck-based were selected as object, from which information continuous truck fleet was truck-specific lane flow samples, technical parameters vehicles determined. Finally, introduced into simply supported different spans, effect at control section calculated compared with according code. The results show that under operation mode “passenger car separation,” when passes through simple support beam, generally does not exceed vehicle code load. When midspan bending moment beam side span middle do However, exceeds ensure safety durability bridge structure, standard value increased by 1.1 times rounded up Highway Bridge Culvert Design Code.
