摘要
为了提高公路设计水平,文章基于土石方对山区高速公路路线的影响,总结了山区高速公路的选线原则和选线步骤,以某山区高速公路为研究对象,分析了土石方计算方法及其对路线纵断面标高的影响.同时,基于土石方分析了路线方案的优化方法,如路改隧、桥改路等,研究成果可为类似项目提供理论指导.
Abstract
In order to improve the level of expressway design,based on the influence of earthwork on the route of mountainous expressway,this paper summarizes the principles and steps of route selection of mountainous expressway.Taking a mountainous expressway as the research object,it analyzes the calculation method of earthwork and its influence on the elevation of route longitudinal section.At the same time,the optimization method of route scheme is analyzed based on earthwork,such as changing road into tunnel,changing bridge into road,etc.The research results can provide theoretical guidance for similar projects.
