This study was supported in large part by the National Science Foundation under Grant GK-18945 and by a NATO Fellowship to the senior author from the Scientific and Technical Research Council of Turkey. The X-ray diffraction work was performed by Kanwarjit S. Chawla; Kutay I. Ozaydin helped to prepare the samples; and Jau S. Jin assisted in conducting the compression tests. The periodic discussions of the fabric work with Raymond N. Yong and Donald E. Sheeran are sincerely appreciated, and the many pertinent suggestions by Wilford R. Gardner and Johannes Bouma have served to clarify the presentation of this work.

N2 - An empirical analysis based on data from 48 one-dimensional compression tests on specimens from 6 different fabric samples is used to examine the influence of void ratio, particle-orientation characteristics, and soil suction on the load-deformation behavior of a kaolinite clay. This is accomplished by approximating the stress-strain response with a two-coefficient hyperbola and studying the variations of these coefficients (one of which is related to the initial tangent modulus and the other to the ultimate strength) with the afore-mentioned intrinsic behavioral parameters. The results indicate that the initial tangent modulus and the strength both increase with decreasing values of the soil suction and the void ratio, but the trends more dere defenitive in the case of strength. Although the effects of particle orientation on the initial tangent modulus were not clear, its effect on the strength parameter and secant modulus was evident.
