摘　　要：通过碎石土回填地基采用高能级强夯技术的工程实例,得到了大量的静载试验、动力触探等现场实测数据,比较完整地反映了12000kN.m高能级强夯的加固效果,分析比较了碎石填土地基夯前和夯后的土工性能指标、地基承载力及变形模量。研究表明,深度12m以内各土层的地基承载力均具有较大幅度的提高,可为其它工程高能级强夯技术的施工、检测及监测提供参考资料。Based on engineering test examples of the subgrade backfilled with gravel soil which is treated by using high energy level dynamic consolidation,a lot of field testing data from static loading tests and dynamic penetration tests are obtained,which completely reflect the treatment effect with 12000kN·m high energy level dynamic consolidation.The geotechnical indices,the bearing capacity and the deformation modulus of the gravel soil foundation before and after the treatment are analyzed respectively,and they reflect the great increase of the bearing capacity of the soils in depth 12m,which provide the reference for the construction,detection and monitoring with high energy level dynamic consolidation.
