DRAINED, UNDRAINED, CONSOLIDATING AND DYNAMIC BEHAVIOUR ASSUMPTIONS IN SOILS

The behaviour of saturated, porous media under dynamic or quasi-static loads was first formulated by Biot (1941, 1960). For dynamic problems a simplification was recently proposed by one of the authors. As the two formulations must coincide over a range of problems and as for slow transients both must be adequately represented by pure consolidation theory, this paper examines the respective ranges of validity by an analytical study of a soil layer subject to a periodic surface force. The analysis also indicates under what conditions such extremes as undrained or quasi-static assumptions can be safely used. Results of the analysis are given in a non-dimensional, generally valid, form and should find practical application in assessing the type of approximation that is applicable in new problems.
