摘　　要：讨论了目前水泥搅拌桩中抗倾覆稳定验算不合理的地方,并且通过分析水泥搅拌桩的失稳机理,揭示出了其失稳形态的多样性。提出了一种采用有限元法计算的水泥搅拌桩的稳定验算方法,并通过实例进行了验证。Irrationality presently existing in checking computations of anti-overturning stability for cement mixing piles has been discussed in this paper. In addition,mechanism of piles＇ losing stability has been analyzed so that the multiplicity of losing stability for cement mixing piles has been revealed. Meanwhile finite element method for checking computations has been proposed and been verified through projects.

关 键 词：水泥搅拌桩 抗倾覆稳定 失稳形态
