Opis:: Uncompacted embankments of certain fine sands exhibit a spontaneous liquefaction potential, which cannot be evaluated basing on undrained shear strength alone. A novel procedure for stability analysis has been developed, basing on Hill's stability criterion and a hypoplastic constitutive law. With given relative densities, assumed initial stress states and variations of perturbation directions, stability or instability of slope sections can be assessed. Catastrophic landslides observed in the past could thus be explained.

Tematy:: finite element method

Opis:: With regard to serviceability state deformations, diaphragm walls and slurry walls cause considerable soil deformations during trench construction. 3-dimensional finite element analyses are able to quantify these deformations. They are compared to measurements and to the results of simplified 2-dimensional models. The dependence of soil stiffness on the actual state can be accounted for by using a hypoplastic constitutive law. Trench geometry and construction sequence are considered as factors of influence. It is shown, how the wall construction process can be modelled at the beginning of an overall 2-dimensional deformation analysis using prescribed initial deformation or stress fields.
