采用刚性桩（CFG桩）加柔性桩（砂桩）的多桩型复合地基加固方法，可以处理地基承载力和变形要求较高的地基。在淤泥地层上修建多层建筑，需要对软土地基进行加固，尝试使用CFG桩加砂桩的多桩型复合地基处治方法，对承载力设计和施工工艺过程进行分析，形成合理的施工方案。工程实践表明采用多桩型加固方法效果较好。

The rigid pile (CFG pile) with flexible piles (sand pile) of multi type pile composite foundation reinforcement method can handle foundation bearing capacity and deformation of high ground .This paper discusses the construction of a multi‐storey building in the silt stratum ,the need for strengthening soft soil foundation ,try to use the CFG pile and sand pile of multi type pile composite foundation treatment method , the bearing capacity of the design and construction process are discussed , the formation of a reasonable construction plan . The engineering practice shows that ,is effective to use multi type pile reinforcement method .
