田林至乐业公路改建工程膨胀土填石路基处理分析

Treatment Analysis of Expansive Soil Rock-filled Subgrade in Tianlin-Leye Highway Reconstruction Project

文章基于田林至乐业公路改建工程,研究了该工程K87+260~K88+520路段膨胀土土基的物理特性、膨胀土的CBR值与其他因素的联系,分析了膨胀土对路基的危害,并提出了膨胀土填石路基处理方法和施工控制措施,旨在对膨胀土路基工程施工提供参考。

Based on the reconstruction project of Tianlin-Leye Highway,this article studies the physical characteristics of expansive soil foundation in the K87+260~K88+520 section of this project as well as the relationship between the CBR value of expansive soil and other factors,analyzes the hazard of expansive soil to the subgrade,and proposes the expansive soil rock- filled roadbed treatment method and construction control measures,aiming at providing the reference for the construction of expansive soil roadbed engineering.
