... depends on the consolidation time. From this point of view the new design method considers the increase of the mobilized frictional force due to consolidation (this was confirmed experimentally by the direct shear test). (3) The degree of consolidation is not constant but it changes due...

..., dated from volcanic activity of Campi Flegrei and Somma Vesuvio , are often remoulded and weathered to clay [Pellegrino, 1991]. In order to investigate the effect of water content on the shear strength characteristics of undisturbed samples of these pyroclastic soils, a series of direct shear tests...

... in field. But, the great expense and efforts are required to perform the in-situ tests. In recent years, the researches(e.g. Krsmanovie 1967) in respect to the direct shear test, using the relatively large specimen which contains weak planes, have been done. Nevertheless, it is difficult to investigate...

... is extracted from the result. The direct shear tests are conducted for soft rock model made by bentonite-cement containing this sinusoidally waved weak layer made by teflon sheet. Then non-linear FEM analyses for this model expressing weak layer by joint elements are carried out and they are compared...
