山区高速公路总体设计原则与路线平纵指标分析

Analysis of the overall design principle and route horizontal and vertical index of mountain expressway

山区高速公路通常多沟壑,纵横交错,地形复杂,地质构造复杂,多发生滑坡、坍塌等地质灾害。文章以G218线那拉提至巴伦台公路工程项目为例,重点分析了高速公路平纵面线形设计的原则和主要方法,以保证该项目的设计符合技术标准,线形设计更加科学合理。

Highways in mountainous areas usually have many ravines,crisscross,complex topography,complex geological structure,and more geological disasters such as landslides and collapses.Taking the Nalati to Barentai highway project of G218 as an example,this paper focuses on the analysis of the principles and main methods of the vertical and horizontal alignment design of the expressway,so as to ensure that the design of the project meets the technical standards and the alignment design is more scientific and reasonable.
