Centrifuge tests have been carried out on kaolin clay slopes subject to variations in surface rainfall and humidity corresponding, at model scale, to successive wet and dry seasons in the field. An analysis of the phase ofepisodic regional softening is presented ...

<p>TxDOT frequently uses Texas Cone Penetrometer (TCP) blow counts to estimate undrained shear strength. However, the current correlations between TCP resistance and undrained shear strength have been developed primarily for significantly stronger soils than ...

Recent research on the delayed failure of cuttings in clay clearly recognizes and predicts progressive delayed failure of deep cuttings. This is due to a combination of strain-softening, weathering, dissipation of negative excess pore water pressure generated ...

Geotechnical Engineering has advanced to the present stage that various types of earth structures can be designed and constructed safely and economically in most instances. However, in some cases, difficulty arises either in the form of failure during construction ...

The study of slope behaviour is a very complex issue, which is not always considered in the right way. In particular the problem of slope movements is often ignored, notwithstanding its relevance in the risk analysis. The paper is devoted to this fundamental ...

Results of torsional ring shear, direct shear, and triaxial compression tests on cohesive soils reveal that the fully softened shear strength is stress - dependent and related to the type of clay mineral and quantity of clay - size particles. An empirical ...

The study involved a laboratory and a theoretical analysis designed to understand whether the use of short fibers increases the shear strength of fissured clays. The laboratory experiments involved the direct shear testing of reinforced and unreinforced clay ...

<p>The in situ wedge shear test was developed as a simpler means than the in situ large shear box test for measuring the undrained shear strength of unsuturated, fissured and/or stony clays. In the past 14 years, two neo versions of this test have been developed ...

The objective of this investigation was to review existing information concerning slope failures in stiff, fissured clays and shales, and to study the influence of lateral stresses on the stress conditions around excavated slopes. These studies, which were ...
