摘　　要：针对回填地区土体的密实程度远远无法达到建筑建设需求的问题,开展回填土地基的强夯加固机理与承载力综合检测技术研究。明确强夯加固中的振动波理论,设计碎石土地基的强夯,实现对回填土地基的加固处理。再通过检测装置设计、加载与检测数据分析,提出一种新的检测技术。将强夯加固机理和综合检测技术应用于实际可以有效促进回填土地基承载力提升,进而增强地基整体稳定性。In response to the problem that the compactness of the soil in the backfill area is far from meeting the requirements of building construction,research on the dynamic compaction reinforcement mechanism and comprehensive bearing capacity testing technology of the backfill soil foundation is carried out.Clarify the vibration wave theory in dynamic compaction reinforcement,design dynamic compaction of crushed stone soil foundation,and achieve reinforcement treatment of backfill soil foundation.A new detection technology is proposed through the design of detection devices,loading,and analysis of detection data.The application of dynamic compaction reinforcement mechanism and comprehensive detection technology in practice can effectively promote the improvement of the bearing capacity of backfill soil foundation,thereby enhancing the overall stability of the foundation.
