摘　　要：根据单桩静载荷试验的结果 ,全面系统地分析了挤扩支盘桩的承载机理、荷载传递性状和FEM模拟结果。通过计算分析 ,指出了承力盘的承力特性具有明显的时间效应和互补效应以及与其他桩型的不同点 。Bearing mechanism, loading transfer behavior and results of FEM simulation of squeezed branch pile are analyzed systematically in this paper based on results of static loading test.Behavior of bearing disks with obvious time effect and its difference from other types of pile are pointed out by means of calculation. Connotation of high bearing capacity and low settlement of squeezed branch pile is explored.

关 键 词：挤扩支盘桩 承载机理 荷载传递性状 FEM模拟
