摘要
To study the soft foundation reinforcing of the large oil tank,the inclination,settlement and reinforcement characteristics of CFG pile composite foundation were studied by FLAC3D.The effects of different parameters on the settlement of CFG pile composite foundation were studied using single variable method.The results show that CFG pile composite foundation can effectively restrict the plane tilt,non-plane tilt,plane settlement and non-plane settlement of tanks,and it can effectively reduce sphere of action of upper loads and restrict ground swell.The maximum horizontal displacement is at the bottom surface of the foundation.Pile length and spacing are the main factors controling the vertical settlement and reinforcement effect.
