Factors that affect the shearstrength parameters of cohesive soil include its structure, clay content, drainage conditions, strain rate and water content (Khan, 1998). A series of tests were carried out on remoulded samples of Kaolin to study its response towards pore pressure development, volume change, failure behaviour during shearing.

This thesis is concerned with an investigation into some aspects of the permeability measurement and permeability characteristics of reconstituted saturated supreme kaolin clay. Development of permeability anisotropy is investigated when the sample has experienced: (1) anisotropic consolidation, and (2) undrained shear. Conventional steploaded consolidation tests, constant flow rate and some ...
VERTICAL AND HORIZONTAL LABORATORY PERMEABILITY MEASUREMENTS IN CLAY SOILS W. B. WILKINSON AND E. L. SHIPLEY 1. INTRODUCTION The soils engineer, in attempting to predict the rate of dissipation of gore water pressure and settlement in clay soils subject to foundation loads, requires the values of both the vertical, c,, and horizontal coefficients of consolidation, c h, of the soil.
Oct 19, 2011· For design purposes, multiple tests for assessment of hydraulic conductivity and the coefficient of consolidation should be made, and a partial factor of safety, depending on the requisite level of safety and the spatial variability of the parameters, should be introduced.

Abstract. Many values of the ratio k max /k min are available for clays and rocks which can be cut for tests in different directions. In comparison, few reliable results are available for noncohesive materials. The hydraulic anisotropy ratios of homogeneous clays, rocks and granular soils appear to be very similar.

Permeability in fluid mechanics and the Earth sciences (commonly symbolized as k) is a measure of the ability of a porous material (often, a rock or an unconsolidated material) to allow fluids to pass through it.. The permeability of a medium is related to the porosity, but also to the shapes of the pores in the medium and their level of connectedness.
