摘　　要：为了研究挤扩支盘桩在水平荷载作用下的工作性状,根据普通桩在水平荷载作用下的微分方程推导出支盘桩的微分方程;采用弹塑性分析法原理和有限差分计算方法推导了支盘桩在水平荷载作用下的计算过程;根据计算结果分析支盘桩工作性状,并与普通桩比较。In order to study the behaviors of squeezed branch piles under lateral loads, the paper has deducted the differential coefficient equation for the squeezed branch piles base on common piles. Besides, the whole calculation processes of squeezed branch piles under lateral loads have been deducted by combining the theories of elasticity-plasticity analysis method and finite difference calculation method. With the calculation processes, we can explore the behaviors of squeezed branch piles, and then compare with common piles to find out which is better.
