某建筑工程部分区域地基采用6000 kN·m能级强夯加固处理,完成了强夯前、后瑞利波测试和重型动力触探试验及夯后静载荷试验,基于检测结果对加固效果进行了详细分析.3种检测方法结果表明:强夯加固处理后地基承载力和压缩模量得到了明显改善,设计要求的处理后土体承载特性参数均达到了相应要求;由于基岩起伏的原因,夯后地基土均匀性较差;综合3种检测方法,可判断出6000 kN·m能级有效加固深度约为6.0~8.0 m.结论以期为类似工程地质条件地基处理提供借鉴与参考.%Dynamic compaction with 6000 kN·m energy-level is adopted in partial building area of one project, where Rayleigh wave test and heavy dynamic penetration test before and after dynamic compaction, static load test after dynamic compaction are carried out. Then, based on the testing results, the reinforcement effect is analyzed. It is showed that the bearing capacity and compression modulus have improved obviously after dynamic compaction, and the bearing capacity parameters can satisfy with relative design requirements. Due to the low and rolling bedrock, the uniformity of foundation soil is bad after dynamic compaction. The effective reinforcement depth of 6000 kN·m level compaction is about 6.0 to 8.0 m. The experience and results in this paper could serve as references in foundation treatment under similar geotechnical conditions.
