摘要
阐述了ＣＦＧ短桩复合地基技术的特点及应用范围，并列举了２个具体的工程实例，经过实践验证该技术是一项省钱、施工质量容易得到保证且能满足复合地基承载力及最终沉降量要求的新技术。探讨了ＣＦＧ短桩复合地基设计中的几个理论问题，并提出了该项技术的进一步研究方向。
Features and application ranges of CFG short pile compound foundation technology are introduced with 2 engineering cases. It is proved that this new technology is economical and easy to satisfy the bearing capacity and the final subsidence volume of compound foundation. Reseach is made on several theoretical problems about the design of CFG short pile compound foundation, and further research direction is proposed.
