摘要
无论是直接式还是平行式的减速车道接环形匝道,其主要目的就是为了保障主线车辆的行驶安全。通过《公路路线设计规范》的修订及《公路路线设计细则》的相关规定,结合G110一间房互通变更设计,由直接式匝道变更为平行式,既保证了车辆行驶安全又方便了施工的设计。文章选用了内蒙古地区互通建设中常用的匝道形式作为研究对象,分别针对不同的连接,得出合理的连接方式,为今后该地区匝道形式设计工作提供可靠的依据。
Both direct and parallel deceleration lanes are connected to the circular ramp,the main purpose of which is to ensure the driving safety of the main line vehicles.Through the revision of＂highway route design code＂and the relevant provisions of the＂highway route design rules＂,combined with the alteration design of G110 at Yi-jian-fang,the direct ramp is changed to parallel,which ensures the safety of vehicle driving and facilitates the design of construction.This paper selects the ramp form commonly used in the construction of Inner Mongolia intercity as the research object,and obtains reasonable connection modes for different connections respectively,so as to provide reliable basis for the design of ramp form in the future.
