Summary
Consolidated-undrained triaxial compression tests were performed on specimens trimmed from eight different labotatory prepared samples of a kaolin clay. The samples covered a wide range of micro-fabrics, and specimens were trimmed parallel and perpendicular to the direction of preferred particle orientation. The micro-fabric of each sample was identified by the combined use of scanning electron microscopy, optical microscopy, and X-ray diffractometry, the latter of which gave a quantitative index that was correlated with the directional dependence of the ultimate strength determined from the triaxial tests.
Résumé
Des essais de compression triaxiale consolidés non drainés ont été faits sur huit échantillons différents de kaolin étant préparé en laboratoire. Ces échantillons représentaient un large éventail de microtextures et étaient taillés parallèlement et perpendiculairement à la principale direction de l’orientation des particules. La micro-texture de chaque échantillon a été déterminée à l’aide de l’usage combiné du microscope électronique, du microscope optique, et de la diffraction des rayons X, cette dernière méthode donnant un indice quantitatif qui fut relié à l’anisotropie de la résistance limite déterminée a partir du triaxial.
