PORE WATER PRESSURE AND SHEER STRENGTH

In a paper prepared for the Institut Technique du Batiment et des Travaux Publics, M. Z. Kurien, University of Kaynatak, shows how the shearing strength of cohesive soils is closely linked to pore water pressure and recalls the impossibility of estimating the latter analytically for the different conditions of loading, deformation, percentage of air in the interstitial fluid and initial conditions. The determination of the shearing strength thus necessarily evolves in relation to the interstitial pressure and to the apparatus used for measurement. To solve this problem, the author is led to examine the extent to which pore water pressure conditions the behavior of the soil, the instances in which this knowledge is unnecessary, the tests already carried out with a view to eliminating this ever difficult measurement, and finally the attempts made to define the behavior of the soil by means of other parameters, the whole being linked to a theory of failure.
