强夯法在市政道路素填土路基处理中的应用

The Application of Dynamic Compaction Method in the Municipal Road Plain Fill Subgrade Treatment

为解决市政道路施工中出现的素填土问题,文章通过案例分析,总结了北环线洛家山路市政道路工程案例项目中素填土路基的处理难点,根据工程项目施工经验,分析了强夯法在素填土层处理中的基本应用思路、施工方案及最终处理效果。根据施工结果可知,经强夯法施工后,土层的压实度、干密度等指标显著上升,地基承载力增强,相关施工技术具有显著效果。

In order to solve the plain fill problem in the construction of municipal roads,this paper summarizes the difficulties in the treatment of plain fill subgrade in municipal road engineering case project of Luojiashan Road on the North Ring Road through case analysis.According to the construction experience of the project,the basic application ideas,construction schemes and final treatment effects of dynamic compaction method in the treatment of plain fill layer are analyzed.According to the construction results,after the construction of the dynamic compaction method,the compaction degree and dry density of the soil layer have increased significantly,the bearing capacity of the foundation has been enhanced,and the related construction technology has significant eff ects.
