Pile-net Composite Foundation Under 3-D Condition

Liu Zhi-gou

Abstract

Based on the software of finite element method(ANSYS 6.1),this paper discusses the bearing performances and deformation characteristics of pile-net composite foundation by numerical analysis.The loading transfer in composite foundation and the settlement and variation of stress of soil and stress ratio of pile-soil law are analyzed under different loading conditions.Meanwhile,it analyzes the influences of elastic modulus of the composite cushions and the physical parameters of the first layer among layered soils of ground on the stress ratio of pile-soil and the settlement and different settlement on soil surface.
