| Abstract: | 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 FLAC3D 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. |
