摘　　要：总结了灰土挤密桩设计及施工中的要点与步骤,特别指出在设计中需要全面考虑碎石桩置换率、地基土粉粒含量ρc、粉土埋置深度、原地基的密实度、场地土的均匀性、施工振动挤密等因素,以使碎石桩计算与实际检测结果尽可能一致。The paper sums up the design of the lime-soil compaction pile and its steps and points out the all-round consideration for the replacement ratio of the gravel pile,the silt content of foundation soil ρc,the embedment depth of silt,the compactness of the former foundation,the uniformity of the site soil and the vibration compaction,so as to make sure the calculation result to be consistent with the factual test result.
