摘　　要：强夯工艺是利用重锤以一定落距自由下落,以强大的应力坡促使土体密实,孔隙水压力、应力等发生变化,达到了强化地基的作用,具有操作便利、流程简单、成本低廉等优势。某公路高填高挖路段的路基采用强夯工艺,保证了路基稳定,提高了地基承载力。The dynamic compaction process uses a heavy hammer to fall freely at a certain drop distance,and a strong stress slope promotes the compaction of the soil,and changes in pore water pressure,stress,etc.,to achieve the role of strengthening the foundation,with advantage of convenient operation,simple process,low cost,etc.The subgrade of a highway section with high filling and high excavation adopts dynamic compaction technology,which ensures the stability of the subgrade and improves the bearing capacity of the foundation.

关 键 词：强夯工艺 路基工程 地基处理
