In this paper we analyse numerically the behaviour of an ideal sandy slope subjected to an earthquake, aiming at exploring the possible triggering and propagation of instability conditions within the domain. At the scope an advanced constitutive model is adopted within a non-linear fully-coupled dynamic finite elements environment.
This note presents the results of constant-volume equivalent-undrained cyclic simple shear tests performed on saturated natural silty soils obtained from two different locations in the Kathmandu valley (Nepal) and characterized by different plasticity. Two simple shear devices were employed: the DSDSS (Double Specimen Cyclic Simple Shear) device and a modified NGI-type DSS device. The above two types of tests complemented each other and jointly covered a wide range of cyclic shear strains amplitudes. Nonlinear soil behavior (i.e.
