摘要: A numerical model is proposed to analyse elastic as well elastoplastic behaviour of stone-column reinforced foundations. The stone-columns are assumed be dispersed within the in situ soil and a homogenization technique invoked establish equivalent material properties for composite. difficulties encountered carrying out analyses composite materials overcome by adopting separate yield function each constituent sub-iteration procedure an implicit backward Euler stress integration scheme. In procedure, equilibrium kinematic conditions implied satisfied both states. The implemented axi-symmetric finite element code prediction made circular footings resting on This indicates good agreement with experimental observation. Finally, new scheme which length variable its examined through example. © 1998 John Wiley & Sons, Ltd.
