浅析公路超高设计

Brief Analysis Road Superelevation Design

公路超高设计是公路几何设计中十分重要的一个方面,是道路设计者非常关注的问题之一。合理的超高设计是保证曲线路段车辆行驶横向稳定和行车舒适安全的主要措施,最新的《公路路线设计规范》(JTGD20-2006)对超高提出了新的要求。本文在正确理解和运用规范的基础上,从超高渐变率、横向力系数。

The road superelevation design is in the road geometry design a very important aspect,is one of path designer very matters of concern.The reasonable superelevation design is guaranteed that the curve road section vehicles travel transversal stability and the driving comfortable security＇s key measure,newest ＂Highway route Design Standard＂ （ITG D20-2006） set the new request to the superelevation.This article in the correct understanding and in the utilization standard＇s foundation,from,the cross-wind force coefficient,superelevation change-over portion＇s establishment aspects and so on superelevation gradation rate carries on the analysis to road superelevation design＇s some questions.
