SHEAR STRENGTH BEHAVIOUR OF SATURATED CLAYS AND THE ROLE OF EFFECTIVE STRESS CONCEPT

This paper discusses the mechanisms controlling the shear strength behaviour of saturated kaolinite and montmorillonite clays from a detailed experimental programme based on certain theoretical considerations. In the light of the modified effective stress concept, which takes into consideration the inter-particle electrical attractive and repulsive forces. An attempt has been made to explain the behaviour of the clays. Eight organic fluids of different dielectric properties, air and water have been used as pore media to vary the inter-particle forces in the conventional box shear apparatus. The experimental results are in qualitative conformity with the modified effective stress concept and the soil strength is significantly influenced by the dielectric properties of the pore medium. Also the influence of failure void ratio is discussed in detail.(a) /TRRL/
