鐘岱輝 傅傳國 （山東建工學(xué)院 濟南 250014）丁大鈞 （東南大學(xué) 南京 210018）[提要] 基于樁體撓曲微分方程，采用帶附加項的富氏級數(shù)逼近樁體撓曲線，對橫向承載樁體，在不同的樁頂約束情況下，與多層地基相互作用問題進行了分析。文中給出了分析過程和數(shù)值算例，計算的結(jié)果同有限元法及實測的結(jié)果作了比較。

Upon the differential equation of pile deflection, the interaction problem of multi-layered soil and lateral-ly-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.
Keywords: laterally-loaded pile; multi-layered soil; interaction, fourier series
