Abstract

Abstract

In order to determine the capacity of composite foundation,the computational model for composite foundation reinforced by stone columns is founded according to load transfer characteristics and failure pattern.The expression of pile-soil stress ratio considering lateral bulging deformation is obtained according to spatial axisymmetric elastic theory and basic assumptions,which includes deformation compatibility and the equilibrium of radial stress on the interface between stone column and soil.The calculation method of the critical edge load and the critical load of composite foundations reinforced by stone columns is provided by the application of Mohr-Coulomb's failure criterion to soil between stone columns.The critical load is approximate to the results of the classical methods for ultimate capacity of composite foundation.
