DRAINED, UNDRAINED, CONSOLIDATING AND DYNAMIC BEHAVIOUR ASSUMPTIONS IN SOILS

摘要: The behaviour of saturated, porous media under dynamic or quasi-static loads was first formulated by Biot (1941, 1960). For problems a simplification recently proposed one the Authors. As two formulations must coincide over range and as for slow transients both be adequately represented pure consolidation theory, this Paper examines respective ranges validity an analytical study soil layer subject to periodic surface force. analysis also indicates what conditions such extremes undrained assumptions can safely used. Results are given in non-dimensional, generally valid, form should find practical application assessing type approximation that is applicable new problems. Le comportement des milieux poreux satures soumis charges dynamiques ou quasi statiques ete analyse pour la premiere fois par Boit Pour les problemes dynamiques, une re...
