摘要
为提高公路隧道路面的安全性,对广东省11条高速公路83座隧道路面的结构类型、横向力系数及交通事故进行了调查研究.结果表明,隧道路面的横向力系数分布曲线呈碗形,相对沥青路面,隧道内水泥路面的横向力系数衰减的较快,隧道内外路面横向力系数差异较大;隧道越长,路面抗滑性能衰减的越快,隧道路面抗滑等级越高,交通事故率越小;隧道水泥路面的年均事故率为沥青路面的1.7倍,隧道沥青路面的安全性优于水泥路面.
In order to improve the safety of highway tunnel pavement,the structure type,and transverse force coefficient and traffic accident of the 83 tunnels of the 11 highway are investigated and studied.The results show that the distribution curve of sideway force coefficient of tunnel pavement is in a bowl form,the sideway force coefficient of cement concrete pavement decays more rapidly compared to asphalt pavement in tunnel,and the difference between the pavement sideway force coefficients inside and outside the tunnel is large.Besides,the longer the tunnel is,the faster the anti sliding performance of the road surface decays;the higher the skid resistance grade is,the smaller the traffic accident rate is.The average annual accident rate of tunnel cement pavement is 1.7times that of the asphalt pavement,and the safety of tunnel asphalt pavement is found to be better than that of the cement pavement.
