Stress state-permeability relationships for fine-grained soils

This Technical Note investigates the possibility that stress state- permeability relationships might be developed for clays within the framework of generalisations already made in the analysis and prediction of soil behaviour. Consolidation and permeability tests carried out on red, brown, black cotton and bentonite soils, chosen for their varying liquid limits, are described. The results are presented and interpreted. For a given void ratio the experimental and predicted permeability coefficients showed a good correlation. The interchangeability of stress state and permeability is discussed.
