Analysis on the consolidation of composite ground with granular columns

Research on settlement calculation method of composite foundation of discrete material piles;

Based on the principle of continuity and harmony of deformation,the stress-strain relationship of the pile and the soil of discrete material piles composite foundation under lateral expansion is analyzed by soil mechanics and elastic theory.

Bearing capacity calculating method of discrete material pile composite foundation;

The bearing capacity of discrete material pile composite foundation was discussed.

The phenomenon that the bearing capacity of the discrete material pile composite foundation is increased by time-varing is fully discussed in this paper.

General analytical solution for consolidation of double-layered composite ground with granular columns;

Analytical solutions for consolidation of composite ground with granular columns under time-dependent loading;

Analytical theory for consolidation of double-layered composite ground with granular columns;

This paper introduces general condition of pile test from test engineering and the design composite pile,and draws some beneficial conclusions through static test of composite pile,physical mechanical test of pile material,chemical analysis and totem appraisal,which to offer a reference for the application of this new-type pile pattern.
