摘　　要：通过在大型垃圾场上建造重型铸造厂房的工程实例,简述振冲法加固成分复杂、深厚垃圾堆场地基的机理和效果。进行单桩复合地基荷载试验并辅以重型动力触探,验证前期的设计假定。通过对检测结果的分析,判断加固效果。It is outlined the mechanism and effect of reinforcing the subsoil made of garbage by vibroflotation, whose composition is complicated and layer is thick, based on actual projects of building heavy-duty casting plant in the garbage site. To validate the design assumption, it is also carried out loading test of single pile composite foundation with heavy-duty dynamic penetration test. Based on the analysis of the test results, the effect of reinforcing is finally judged.

关 键 词：振冲法 单桩复合地基 荷载试验
