Analytical techniques available for numerically solving nonlinear stress-deformation problems of a ground are not applicable to those cases where the highly dilatant materials are involved, as Poisson's ratio ν in these analyses exceeds 0.5,which consequently violates positive definite condition of the stiffness matrix used in these analyses.In a new analytical technique proposed herein volume change of a soil is conceptionally divided into two components : consolidation and dilatancy, which are computed independetly. Through this procedure the new analysis within basically the same framework as the conventional analytical method can readily be applied to any soil materials with arbitrary dilatant behaviors. Analyses carried out for some typical geotechnical problems employing this new technique reveals the effectiveness of the proposed method.
