Modelling of cyclic soil degradation: Development of a cyclic accumulation model and the application to a gravity based foundation

This thesis entitled "Modelling of cyclic degradation - Development of a cyclic accumulation model and the application to a gravity based foundation" presents a new soil model to analyse the behaviour of undrained soils subjected to cyclic loading. Cyclic loading on offshore support structures for wind-turbines results in complex design...

A design-oriented numerical investigation seismic soil-structure interaction

Presented here is the numerical investigation on seismic soil-structure interaction applying features of a rather non-conventional earthquake design. The examination focuses on the Groningen site conditions which lately experienced an induced-type of earthquake. A unique situation calls for a suitable seismic design for both existing and new...

The influence of freeze-thaw cycles on the shear strength of Illite clay

Thermo-active structures, such as energy piles, are used to store and extract heat energy from soil. In areas with seasonal freezing and thawing, such infrastructure is subjected to changes in the soil structure and, consequently, the soil strength. This research investigated the influence of repeated freeze-thaw (FT) cycles and different...

In-pit co-disposal of tailings in an onshore dredge mine

This research aims to provide an understanding of the behaviour of co-disposed coarse (sand) and fine (clay and silt) tailings when discharged into an onshore dredge pond, and the dependence of that behaviour on the sediment composition. This understanding contributes to the ultimate goal of finding a method by which fine tailings can be...
