摘　　要：通过对某工程灌注桩质量事故调查,分析了混凝土工作性和施工工艺对灌注桩大流动混凝土质量的影响。提出了在重视混凝土流动性同时不能忽视混凝土的粘聚性和抗离析性对灌注桩大流动混凝土质量的影响;并提出了预防此类质量事故发生的措施和建议。Through to the investigation of some project concrete filling pile quality accident, It has been analyzed that the concrete operating characteristic and the construction craft influence the quality of filling pile with greatly mobile concrete. While It is proposed that we should take the mobility of concrete not to be able to neglect the cohesive properties and the anti-segregation of the concrete which influence the quality of the filling pile with greatly mobile concrete; Be also put forward preventing from the measure and the suggestion of this kind of quality trouble occurrence.

关 键 词：灌注桩 大流动混凝土 粘聚性 抗离析性
