Abstract

Based on the software of finite element method(ANSYS6.1),the paper discussed the bearing and settlement performances of pile-net composite foundation by means of numerical analysis.the loading transfer in composite foundation and the settlement and the variation of stress of soil and stress ratio of pile-soil law are analyzed under different loading conditions.At the same time,it analyzed the influences of elastic modulus of the composite cushions of layer and the physics parameter of the first layer soil among layers soils of ground on the stress ratio of pile-soil and the settlement and differential settlement on soil surface.
