摘要
通过自行开发的三轴加速度仪对某山区高速公路的八条隧道的不同位置的路面抗滑性能进行测定,分析了不同路面结构和纵坡下的隧道路面抗滑性能的变化规律.随后,采用汽车动力学仿真技术对附着系数变化下的隧道行车安全进行分析,揭示了事故产生的主要原因.最后,结合国内外隧道路面铺装技术对隧道路面的结构设计提出合理建议.
The anti-sllde performance of tunnel road surface is measured at different positions of eight tunnels ofa montanic expressway by self-developed three-axes acceleration apparatus. The general alteration regulation of anti-slide performance of tunnel road surface with different structure and slope is analyzed, and its effect on driving safety is probed based on the vehicle dynamic simulation technique. Finally, the reasonable suggestiom for tunnel road surface structure design are proposed based on tire relative research.
