对高速公路超高过渡段设计的探讨

Study on Highway Superelevation Transition Segment Design

公路超高是在公路弯道中,为了消除汽车在圆曲线上行驶时产生的离心力,在设计时将路线做成外高内低的单向坡,以消除汽车的离心力。超高过渡段的设计是否合理,影响着行车安全和路面排水,论文根据多个高速公路项目的超高设计经验,对超高过渡段设置的不同形式进行了探讨,为今后公路中的超高设计提供一些成熟经验。

Highway is in highway curve, in order to eliminate the centrifugal force produced when the automobile runs on the circular curve, in the design the route made high low of unidirectional slope, to eliminate the centrifugal force of a car. Ultra high transition section design is reasonable, affecting the traffic safety and road surface drainage, this paper according to the highway project of super high design experience, of ultra high transition period setting different forms are discussed, for future highway Superelevation Design provide some mature experience.
