摘　　要：以某超长群桩基础为算例,运用有限差分软件FLAC3D进行超长群桩效应的数值计算,分别得出低承台超长群桩桩身轴力、桩侧摩阻力及桩身沉降的特性,并将其与超长单桩的计算结果进行对比,初步探讨超长群桩的群桩效应。Taking a very long group pile foundation as an example, the authors in this paper make the numerical calculation of the effect of very long group piles, using the finite difference software FLAC^3D and respectively obtain the characteristics of the shaft axial force, side frictional resistance and settlement of the piles used for low-lying pile cap. Meanwhile, the authors also compare the characteristics with the calculation results of a single very long pile and preliminarily study the effect of the group piles.
