Effective stress soil mechanics
WebThe traditional approach in rock mechanics has been to use the effective stress, as defined above, to explain the role of pore pressure in the failure of intact rock. The effective stress concept, however, was developed in the context of soil mechanics, in which the solid matrix is not equivalent to that of most rocks. Intergranular cementation ... WebDuring critical state flow of soil, the undrained cohesion results from effective stress and critical state friction, not chemical bonds between soil particles. ... Critical state soil mechanics analyses the bearing capacity of soft clay on the wet side of critical state in terms of a perfectly plastic material with rapid undrained "apparent ...
