A future development site of a housing estate, an abandoned-brick yard with clayey slopes was studied in details to assess slope stability and to calculate the factor of safety. The Oligocene clay, the former raw material, is divided into two different geotechnical units in the clay pit. The lower one consists of grey impermeable clays while the upper unit is characterised by yellowish weathere...

Three case studies involving the use of numerical models are presented in this paper. First, a comparison of FE modelling of a deep excavation is made using 2-D finite element software, SAGE-CRISP and PLAXIS. In the second study, benchmarking is made between results obtained from 2-D FE modelling using PLAXIS and well-established 3-D centrifuge studies for the case of an existing single pile an...

Liquefaction is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid cyclic loading. Liquefaction and related phenomena have been responsible for huge amounts of damage in historical earthquakes around the world. Modeling of soil behavior is the main step in soil liquefaction prediction process. Nowadays, several constitutive models for sand...

The field performance of a geotechnical structures including its failure mechanism should be evaluated in detail before construction in order to minimize the possibility of potential failure. In this paper, the application of soil nailing system is documented in a detailed based on case study in the north of Tehran, Iran. The total excavation depth for a 15 storey residual building wall brought...

Introduction the expansive soil shows obvious volumetric changes under changing moisture conditions. these volumetric deformations usually result in differential movements of shallow foundations resting on it. consequently, structural damages could happen if no special measures would have been taken during the design process. this article illustrates the possibility to predict such movements us...
