为提高高速公路膨胀土路基施工技术水平,本文在介绍膨胀土基本特征的基础上,将膨胀土路基分为路堤与路堑两方面对其施工技术进行研究,针对膨胀土路基施工时常见问题进行分析提出相应解决方法,并将膨胀土施工技术应用于实际工程并对其路基顶面弯沉检测与路表中心沉降观测,结果表明:经过严格施工技术控制后其弯沉值与沉降值均满足规范要求,能较好解决膨胀土地基问题。
In order to improve the construction technology of expansive soil subgrade in expressway, based on the introduction of the basic characteristics of expansive soil, this paper studies the construction technology of expansive soil subgrade into embankment and road cutting, and analyzes the common problems in the construction of expansive soil subgrade The corresponding solutions are put forward and the expansive soil construction technology is applied to the actual project. The deflection test of the subgrade and the settlement of the road surface center are observed. The results show that the deflection and settlement value of the expansive soil satisfy the standard after the strict construction technology control Requirements, can better solve the problem of expansive soil foundation.
