摘要
基于平面应变问题的假定前提，应用弹塑性理论，分析了灰土挤密桩成孔过程中孔周土体的应力变化，建立了孔周土体有效挤密半径的计算公式．
In view of the premise of plane strain problem and by applying elastoplastic theory, the stress regularity of the soil around the hole in the hole formation with lime soil compaction pile is discussed, and a formula on the effective compaction radius of the soil around a hole is established.
