高速公路平纵线形指标及其对行车安全性的影响分析

Analysis on the Horizontal and Vertical Alignment Indexes of Expressway and Their Influence on Driving Safety

为保证高速公路路线设计质量,文章总结了平纵线形指标分类方法和选择原则,结合现行规范探讨了平面线形和纵断面线形指标的选取方法。同时,以某高速公路研究对象,将其划分为若干个评价单位,分析了弯坡路段的行车安全性,研究成果可为类似项目提供理论指导。

In order to ensure the quality of expressway route design,this paper summarizes the classification methods and selection principles of horizontal and vertical alignment indexes,and discusses the selection methods of horizontal alignment and vertical alignment indexes in combination with the current specifications.At the same time,an expressway is taken as the research object and divided into several evaluation units,and the driving safety of the curved slope section is analyzed.The research results can provide theoretical guidance for similar projects.
