摘　　要：为研究粤东山区高液限土路堤强夯处理效果,以大(埔)丰(顺)(五)华高速公路丰顺至五华段典型高液限土路堤为依托,基于试验段现场实测数据,分析了强夯后路堤压实度变化情况,总结了点夯和满夯施工后路堤总体沉降规律,通过对比不同夯击能下夯击沉降差与夯击击数关系曲线,得到了不同夯击能下终锤标准的点夯击数,为今后粤东山区类似条件下高速公路路堤强夯设计与施工提供了借签和参考。In order to research the treatment effect of dynamic compaction test in high liquid limit soil embankment,which is wide spread in mountains of east Guangdong Province,relying on the typical high liquid limit soil embankment of Dabu Fengshun Wuhua extra-long highway in the road section of Fengshun to Wuhua,based on the results of test section,analyzed the change on compactness of embankment after dynamic compaction treatment,summarized the rules of embankment subsidence after point compaction test and full compaction test.By comparing the relationship between the subsidence difference and tamping times under different tamping energy,obtained the tamping times of different tamping energy in point compaction test,which can provide reference for the design and construction of similar project in mountains of east Guangdong Province in the future.
