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.
Some parts of a construction area of the foundation with 6000 kN · m level dynamic compaction reinforcement, completed before and after dynamic compaction Rayleigh wave test and heavy dynamic penetration test and ram static load test, based on the test results of the reinforcement effect The results of three kinds of testing methods show that the bearing capacity and compressive modulus of foundation after dynamic compaction have been obviously improved, and the bearing capacity parameters of the designed soil meet the corresponding requirements. Due to the fluctuation of bedrock, After the compaction, the homogeneity of the soil in the foundation is poor. According to the three detection methods, it can be concluded that the effective strengthening depth of 6000 kN · m level is about 6.0 ~ 8.0 m. Conclusion It is expected to provide reference and reference for the treatment of similar engineering geological conditions.
