公路施工中的软土路基施工技术

Soft Soil Subgrade Construction Technology in Highway Construction

软土在多个公路建设区域具有较大面积分布,软土路基极易在上部荷载作用下出现大幅度沉降,威胁公路运行安全。因此,以一个公路施工项目为对象,简单介绍了软土路基施工技术,论述了软土路基施工效果。得出:泡沫轻质土、CFG桩加固后的路基整体性能优良,可以有效减少路基差异沉降。

The soft soil is widely distributed in many highway construction areas,and the soft soil subgrade is prone to large settlement under the action of upper load,threatening the safety of highway operation.Therefore,taking a highway construction project as the object,this paper briefly introduces the construction technology of soft soil subgrade and discusses the construction effect of soft soil subgrade.It is concluded that the overall performance of the subgrade strengthened with foam light soil and CFG piles is excellent,which can effectively reduce the differential settlement of the subgrade.
