摘　　要：针对CFG桩和夯实水泥土桩在松散砂土中成桩常出现塌孔、断桩的问题,通过改进施工机械和施工技术手段,优化了在松散砂土中成CFG桩和水泥土桩的成桩质量,进而优化了工程施工质量。Aiming at hole collapsing and pile breaking problems occurred in CFG pile and compacted cement soil pile of unconsolidated sandy soil, through improving construction machine and construction technical method,the pilling technology of CFG pile and cement soil pile in unconsolidated sandy soil was optimized therefore optimized engineering construction quality.

关 键 词：CFG桩 夯实水泥土桩 差异沉降 质量优化
