On the treatment method of highway foundation in collapsible loess area

路基是公路的主要承重层,路基施工过程中的湿陷性黄土对路基质量的影响极大。因此,湿陷性黄土地基的处理对提高该地区公路项目的整体质量至关重要。文章以G341线环县(二十里沟口)至车路崾岘(甘宁界)公路为例,就本项目中对湿陷性黄土地基采用的处理方法进行了分析总结,为类似工程的建设提供参考。

Subgrade is the main bearing layer of highway,collapsible loess in the process of subgrade construction has a great impact on the quality of subgrade.Therefore,the treatment of collapsible loess foundation is very important to the improvement of the overall quality of highway projects in this area.Taking the highway from Huanxian(shiligokou)to Chelu Yaoxian(Ganning boundary)of g341 line as an example,this paper analyzes and summarizes the treatment methods of collapsible loess foundation in this project,so as to provide reference for the construction of similar projects.
