| 摘 要： | 公路路线设计规范要求在当条件受限时,隧道出口至前方互通式立体交叉减速车道渐变段起点的距离不应小于1000m。在山区高速公路的立交设计中可能难以满足要求。结合实际对隧道出口至互通式立交最小安全距离进行浅析。

| Abstract: | It is specified by Specification of Highway Routine Design that the distance from tunnel exit to starting point of gradual change section of deceleration lane of interchange shall be no less than 1000m under limited conditions,which is hard to meet interchange design requirement for expressway of mountainous area.Combined with practical situation,the minimum safe distance from tunnel exit to interchange is analyzed briefly. |
