摘　　要：利用大型有限元通用软件ABAQUS建立PCC桩水平承载特性有限元分析模型,并用足尺试验进行了对比分析,表明该模型是合理可行的.进而,对等截面的PCC桩与实心灌注桩的水平承载性能进行了详细的对比.结果表明,作为弹性长桩,PCC桩较实心灌注桩具有更好的抗水平荷载的能力;作为刚性短桩,等截面的PCC桩和实心灌注桩的水平承载性能差别不大.By using the general FEM software ABAQUS,this paper analyzed the behavior of PCC pile under lateral load according to the full-scale model test,and compared the behavior of PCC pile and bored pile under lateral load.The results indicated： as a flexible pile,the displacement of PCC is far less than the displacement of bored pile with equal section,while the moment of PCC is slightly larger than the moment of bored pile;as a rigid pile,the lateral behavior capacity between PCC pile and bored pile had little difference.Therefore,the lateral bearing capacity of PCC is better than the bored pile as a flexible.
