摘　　要：为提高双车道公路隧道群隧道间紧急停靠带安全设置水平,分析了在隧道出入口白洞效应和黑洞效应影响下,因紧急停靠带位置设置不当而可能引起的追尾碰撞事故及其发生过程,并以此为依据,建立了紧急停靠带与隧道出口安全距离解析方程组和紧急停靠带与隧道入口安全距离解析方程组,通过求解这两个方程组可获得紧急停靠带与隧道进出口应保持的最小安全距离。最后,用实例的方式介绍了如何应用本方法。In order to improve the safety level of emergency parking strip between tunnels of two-lane highway tunnel groups, rear-end collision as well as collision process caused by the wrong location of emergency parking strip affected by tunnel white hole effect and black hole effect are analyzed. Based on this, the analytic equations of distance between emergency parking strip and tunnel exit are established, as well as the analytic equations of distance between emergency parking strip and tunnel entrance. The least safety distance between emergency parking strip and tunnel exit or tunnel entrance can be acquired by solving the two equations. Last, how to use the method is introduced by instance.
