摘　　要：在既有宕渣路基建设条件下,采用强夯进行道路地基处理。通过对强夯试验段进行分析与总结,采用“硬壳层整体刚度”设计理念,提出合理可行的强夯施工工艺,结合路基浅层冲击压处理,取得了良好的路基处理效果,避免对欠固结状态下既有路基的重复翻挖,切实保障了工程的经济性,获得了良好的社会效益。Under the construction conditions of the existing slag subgrade,the dynamic compaction method is used to treat the road subgrade.By the analysis and summary of the dynamic compaction test section,the design concept of"integral stiffness of hard shell"is used.The reasonable and feasible dynamic compaction construction technology is put forward.Combined with the shallow impact pressing treatment of subgrade,the good treatment effect of subgrade is achieved.The repeated excavation of the existing subgrade under non-consolidation is avoided.The economy of the project is effectively guaranteed.The good social benefit is achieved.
