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>This manual is intended to enable the reader to have the necessary special equipment made, and to perform and evaluate all three versions of the wedge shear test. A diskette containing the relevant computer programs and typical input data is to be found ...

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 ...
