摘　　要：基于桩体挠曲微分方程,采用带附加项的富氏级数逼近桩体挠曲线,对横向承载桩体,在不同的桩顶约束情况下,与多层地基相互作用问题进行了分析.文中给出了分析过程和数值算例,计算的结果同有限元法及实测的结果作了比较.Upon the differential equation of pile deflection, the interaction problem of multi-layered soil and laterally-loaded pile with different top restriction is studied. The deformation of the pile is closed with Fourier Series accompanied by additional terms. The analytical procedure of the problem is presented. The results of several numerical examples are compared with those obtaimed by FEM and field measurements.
