摘　　要：强夯是一种快速、有效且经济的地基加固处理方式.本文从路基地质条件、加固前后的路基土体物理力学性质以及沉降监测数据等几个方面论述了强夯在路基加固处理中的应用.研究表明:利用所有夯点最终2击在地基土中用重力击打贯入体时,贯入体进入土体中的深度的均值不大于5.0cm^6.0cm和夯沉量的均值不小于50cm^60cm来为强夯质量所控制是可以的.地基土层被强夯处理后压密而引起的地基表面下沉量明显降低,地基土体所能承受荷载的能力被强夯处理后明显增强.Dynamic compaction is a fast, effective and economical foundation reinforcement approach. In this paper, the benefits from the dynamic compaction, dynamic compaction method in terms of strengthening mechanisms have been described, and geological conditions from the roadbed, the construction process, reinforced soil embankment before and after the physical and mechanical properties and subsidence monitoring data discussed several aspects of a strong ram a highway embankment in subgrade law reinforcement applications. Studies suggest that： according to the average volume in the ram sink 50 cm ～ 60 cm, each ram hit the last two points of penetration is less than 5. 0cm ～ 6. 0cm on average for compaction quality control is feasible. After dynamic compaction, the foundation soil bearing capacity significantly improved, a small amount of foundation settlement.
