摘　　要：水泥搅拌桩成桩质量影响因素众多,控制不力往往达不到预期效果。在正式施工前应根据成桩质量的影响因素,对水泥搅拌桩的地区适用性展开研究。文章结合贵州某高速公路试验段水泥搅拌桩成桩质量缺陷的研究工作实例,从水泥搅拌桩成桩质量的影响因素出发,制定室内试验和现场试桩方案,结果表明土的含水量、塑性指数和有机质含量等是影响该地区水泥搅拌桩成桩质量的主要因素。The quality of the cement mixing pile is affected by many factors.Lack of control will lead to the failure of expected result.Before formal construction,region suitability according to the influence factors of the quality of cement mixing pile should be researched.Combined with the example of a highway testing cement mixing pile quality defect research in Guizhou,indoor test and field test pile program were made,considering influence factors of the cement mixing pile quality.The results show that soil moisture content,plasticity index and organic matter content were main influence factors of the cement mixing pile quality in the region.
