| 摘 要： | 为研究隧道进出口路面结构抗滑性能,对广惠高速萝峰隧道、望牛岭隧道、青山隧道的横向力系数、隧道洞口附近路段工况进行调查分析,调查结果表明,进入隧道内横向力系数逐步降低,路面横向力系数隧道内低于隧道外,隧道内易发交通事故,需要进一步完善设计与施工方案,同时刻槽具有较好构造深度,抗滑能力良好。

| Abstract: | In order to research anti-slide performance of tunnel entrance and exit,this paper analyzes lateral force coefficient and road conditions near the tunnel entrance of Guanghui expressway Luofen tunnel,Wangniuling tunnel and Qingshan tunnel.The results show that lateral force coefficient is gradually reducing in tunnel.It is suggested that design and consturction should be improved and notch groove should be used for it's good texture depth and anti-slide performance,the lateral force coefficient of tunnel in... |
