This book was released on 1991 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2017-01-16 with total page 528 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this spirit, the ATMSS International Workshop “Advances in Laboratory Testing & Modelling of Soils and Shales” (Villars-sur-Ollon, Switzerland; 18-20 January 2017) has been organized to promote the exchange of ideas, experience and state of the art among major experts active in the field of experimental testing and modelling of soils and shales. The Workshop has been organized under the auspices of the Technical Committees TC-101 “Laboratory Testing”, TC-106 “Unsaturated Soils” and TC-308 “Energy Geotechnics” of the International Society of Soil Mechanics and Geotechnical Engineering. This volume contains the invited keynote and feature lectures, as well as the papers that have been presented at the Workshop. The topics of the lectures and papers cover a wide range of theoretical and experimental research, including unsaturated behaviour of soils and shales, multiphysical testing of geomaterials, hydro–mechanical behaviour of shales and stiff clays, the geomechanical behaviour of the Opalinus Clay shale, advanced laboratory testing for site characterization and in–situ applications, and soil – structure interactions.

Download or read book Settlement of Compacted Clay in a Cyclic Direct Simple Shear Device written by H-H Chu and published by . This book was released on 1992 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The results of 36 cyclic strain-controlled direct simple shear tests on a low-plasticity compacted clay are presented and analyzed. The tests were conducted in a Marshall Silver-type device, which utilizes the Norwegian Geotechnical Institute (NGI) type of short cylinder specimen confined in a wire-reinforced rubber membrane. Three degrees of compaction achieved by the modified compaction test are encompassed: (1) below the optimum moisture content, (2) at the optimum, and (3) above the optimum. All specimens were sheared under the same vertical consolidation stress. In each test the cyclic shear strain amplitude, ?c, was controlled, i.e., the cyclic tests were strain controlled. The range of ?c was between 0.008 and 4.6%. The test results show a very consistent behavior of the clay at all three moisture contents. At small cyclic shear strains below ?c ? 0.1%, the stress-strain behavior is slightly nonlinear, i.e., close to linearly elastic, and the vertical settlement is negligible. In some tests such nondestructive behavior was recorded up to ?c ? 0.2%, showing that for the clay tested, the volumetric threshold shear strain, ?tv, ranges between 0.1 and 0.2%. At ?c larger than ?tv the cyclic stress-strain behavior becomes nonlinear and a continuous settlement with the number of cycles, N, occurs. The results do not show a clear relation between the rate of settlement with N and the degree of the compaction and moisture content. For different moisture contents, similar settlements were obtained for given ?c and N. The study also shows how to arrange the specimen setup and measuring system to eliminate the effect of the simple shear apparatus compliance. In such an arrangement very small shear strains can be applied and successfully measured.

Available in PDF, EPUB and Kindle. Book excerpt: Several series of consolidated undrained direct translatory shear (DTS) and direct simple shear (DSS) tests have been performed on two sensitive clays of eastern Canada. Before shearing, the specimens were consolidated to pressures varying between 20 and 350 kPa. The investigation was performed with the aim of determining both the anisotropic nature and the effect of the consolidation pressure level on the response of the tested clays. To study the anisotropic nature of the sensitive clays, the specimens were cut at various inclination angles with respect to the in-situ horizontal plane, consolidated to predetermined normal stress levels, thus altering the fabric, and then sheared under undrained conditions. The range of the normal stress levels used was such as to be able to investigate the response of the soil from very high overconsolidation ratios to normally consolidated or destructured states. The results show that for consolidation pressures less than the preconsolidation pressures of the inclined specimens, the undrained shear strengths are anisotropic. In this case, the specimens that are sheared along the horizontal in-situ direction show the lowest strength, while those that are sheared along the vertical in-situ direction have the highest strength. However, for the specimens that are consolidated under pressures in excess of the preconsolidation pressures, the undrained shear strengths are found to be independent of shearing direction.
