Modeling of Large Diameter Piles in Soil Formations Including Soft Clay

Soft Soil Seismic Design Spectra Including Soil-structure Interaction

Design spectrum is known as an essential tool in earthquake engineering for calculation of maximum (design) responses in a structural system. Soil-structure interaction (SSI), as a phenomenon of coupling of responses of a structure and its underlying soil, was explored after introduction of design spectra and has not been taken into account in developing a design spectrum traditionally. To cons...

uncouple nonlinear modeling of seismic soil-pile-superstructure interaction in soft clay

this paper presents the numerical analysis of seismic soil-pile-superstructure interaction in soft clay using free-field soil analysis and beam on winkler foundation approach. this model is developed to compute the nonlinear response of single piles under seismic loads, based on one-dimensional finite element formulation. the parameters of the proposed model are calibrated by fitting the experi...

Centrifuge modelling of sand compaction piles in soft clay under embankment load

Sand compaction piles are used in practice for ground improvement of soft subsoil in order to accelerate consolidation, reduce compressibility, and increase strength. The current design procedure of sand compaction piles is based on simple empirical calculations, which does not take full account of the sand pile behaviour. This research project investigates the behaviour of a base reinforced em...

Gas migration process in deformable clay formations

Introduction To predict the evolution of a Geological Disposal Facility, it is necessary to understand the interaction between a number of key features and process and its impact on the long-term behaviour. Central to these issues are the mechanisms and process that govern the movement of gases in a repository. Linking the gas transport to the stress-strain response of the engineering systems b...
