摘要
隧道路面抗滑能力与隧道事故发生率有直接的相关性,而且不同的路面铺装形式,其抗滑能力也不同。采用横向力系数检测车对纵向刻槽的水泥路面、沥青路面和横向刻槽水泥路面三种不同路面结构的隧道横向力系数进行检测,结果表明,具有纵向刻槽形式的水泥路面具有较好的抗滑性能,这说明对隧道内路面铺装水泥路面时采用纵向刻槽措施可以有效提高路面抗滑性能,减少隧道内交通事故的发生。
Skid-resistance of tunnel pavement is direct correlated with accident rate. Different pavement shape has different skid-resistance. Using lateral force coefficient check-out car can check out the tunnel lateral force coefficient of longitudinal-devilling cement road, bituminous pavement, lateral -devilling cement road, which turns out longitudinal-devilling cement road has better skid resistant.That shows adopting longitudinal-devilling measure during paving cement road in tunnel can increase effectively pavement skid resistant and decrease traffic accident in tunnel.
