摘要
采用手工铺砂法和摆式仪对贵州、云南等省的隧道路面抗滑性能进行了现场实测 ,调查的结果表明 ,隧道水泥混凝土路面的抗滑耐久性较差 ,使隧道交通存在着一定的安全隐患。分析了隧道内部特有环境对隧道路面抗滑性能的影响 ,并针对隧道路面类型的选择 。
On the basis of the tests of texture depth and pendulum tester,the characteristics of skid resistance of tunnel pavements are surveyed in Guizhou Province, etc. The results of texture depth (TD)and skid resistance value(SRV)show that the skid resistance of cement concrete pavements in tunnels can not long endure,which increases the possibility of accidents in tunnels.After analyzing the factors causing a relatively poor skid resistance to tunnel pavements, some methods to improve the capacity of skid resistance are suggested in accordance with the type of pavements used in tunnels.
