摘　　要：指出渣土桩是基于强夯与灰土挤密桩加固理论的新型地基加固技术,研究了渣土桩处理杂填土地基的工作机理,以及形成的复合地基的质量控制措施,并进行了地基处理前后承载力对比分析。结果表明,采用渣土桩复合地基的承载力能满足铁路路基150 kPa的设计要求;渣土桩的质量控制措施和施工工艺能为后续工程提供设计、施工依据。This paper pointed out that muck research pile was new foundation reinforcement technology based on dynamic compaction and compaction pile reinforcement theory,studied the work mechanism of muck pile treatment of miscellaneous fill,and the quality control measures of formation of composite foundation,and made contrast analysis on bearing capacity of before and after foundation treatment.The results showed that： the bearing capacity using muck pile composite foundation could meet the design requirements of railway subgrade 150 kPa,the quality control measures and construction technology of muck pile could provide design,construction basis for follow-up engineering.
