摘　　要：用大型有限元软件ABAQUS分析了挤扩支盘桩的抗拔特性,并与抗压特性进行了比较。分析结果表明,承力盘的形状、间距、大小等参数对支盘桩的抗压、抗拔承载力存在一定影响,其中对抗拔承载力的影响程度较大。The extraction-resistant behaviors of squeezed branch piles are analyzed with large FEM software ABAQUS and compared to the compression-resistant behaviors.The results have shown that such parameters as the figures,distanced between and sizes of force-bearing disks have a definite influence on the compression and extraction-resistant bearing capacity of these piles and have a greater influence on the extraction-resistant one among other things.
