Book Description
A comprehensive series of undrained shear tests were performed on a lean sensitive marine clay in both the normally consolidated and overconsolidated state. The types of tests performed included triaxial compression and extension and direct simple shear tests on K0-consolidated specimens. It was found that the clay is highly anisotropic with respect to its undrained shear strength and its stress-strain characteristics. Undrained shear strengths from compression tests were 1.7 to 1.8 times greater than from extension tests. Undrained strengths from direct simple shear tests were somewhat higher than the strengths from extension tests. Similar anisotropic behavior was also observed for undrained moduli. Failure strains were found to be influenced by the stress system during consolidation and the mode of shear. K0-consolidated specimens sheared in compression failed at extremely low strains and showed significant strain softening. The importance of these observations as they may relate to problems of undrained stability is discussed.

Simple Shear of an Undisturbed Soft Marine Clay in NGI and Torsional Shear Equipment

Book Description
A series of undrained, simple shear tests were performed on undisturbed, soft, marine clay from the continental slope of Israel in a direct simple shear device (NGI) and in a new torsional shear apparatus. The new apparatus is described, and the problematics of simple shear testing in both devices are discussed. Most previous torsional shear testing on clays reported in the literature has been performed on remolded specimens. In order to prepare specimens from undisturbed samples of the soft, marine clay, whose natural moisture content is close to the liquid limit, a special preparation technique was developed. A comparison of the stress-strain curves obtained in the two devices indicates higher stiffness and strength of the specimens tested in the torsional equipment; a similar observation has been reported in the literature from tests on sands and remolded clays. It is the authors' view that the main cause for the discrepancy is flexibility of the confining membrane in the NGI equipment. In view of the relevance of simple shear conditions to actual field problems, it appears important to further clarify this difference and to establish an accepted method for simple shear testing in the laboratory.
