摘　　要：针对粉喷桩施工过程中对土体扰动的情况,提出了粉喷桩对桩周土体扰动的弹性阶段及塑性阶段的径向应力、切向应力变化及径向的位移解析解,并求解出塑性区与弹性区边界大小的解析解。In this paper, the soil disturbance induced by the construction process of dry-cement jet mixing columns, the change of the radial stress and the tangential stress, and the analytial solution of the radial displacement are all analysed in this paper, the analytial solution to the boundary between the plastic section and the elastic section is also included.
