## Abstract Projection, or conjugate gradient like, methods are becoming increasingly popular for the efficient solution of large sparse sets of unsymmetric indefinite equations arising from the numerical integration of (initial) boundary value problems. One such problem is soil consolidation coupl

This paper presents a variation of Biot's consolidation theory for analysing problems involving unsaturated soils, and implemented using the "nite element method. The numerical method is applied to a few geotechnical problems as examples and the results obtained are compared to some published data.
