摘　　要：利用滑移线理论对挤扩支盘桩在单肢挤扩过程中下肢土体进行分析,建立了支盘桩挤扩过程中土体的滑移线场并得出土体的应力场,结果表明:挤土装置所施加的作用力并不是随着挤扩角度的增大而不断的增大,而是随着挤扩角度的增大不断减小。Analyze the soil under the lower arm of the squeezed pile during the single process under every angle with slip-line method.The paper establish a slip-line field in the area of the soil,and get the stress filed.The results show that the load from the equipment is not increase with the squeezed angle,it gradually reduced with the angle.

关 键 词：挤扩支盘桩 滑移线场 应力场
