Centrifuge modelling of plate bearing tests

Current guidance given on plate bearing testing of granular soils suggests that the plate be at least five times the nominal size of the coarsest material. However this limiting ratio can have a huge influence on the reaction load required from plant and resources when conducted to confirm strength parameters used in the design of the sub grade...

On the modelling of piles in sand in the small geotechnical centrifuge

The use of a geotechnical centrifuge for properly capturing the mechanisms in the sand adjacent to a foundation pile is well established. Larger centrifuge facilities were previously preferred over small centrifuges, because of the difficulties of the required miniature instrumentation. The technology since then has moved on and recent technical...

Examples of the influence of centrifuge modelling on offshore geotechnical engineering

Offshore geotechnical engineering is characterized by unusual soil and loading conditions, a continuously moving frontier resulting in the requirement for innovative geotechnical solutions, and the very high cost associated with in-situ soil characterization and field testing in remote and deep oceans. As a consequence, offshore engineering...

High shear capacity ribbed piles

Ribbed bored piles are known to give increased shaft capacity in comparison to conventional straight shafted bored piles. The commercial benefit of greater pile capacity is cheaper foundations. Significant environmental benefits will also accrue from the use of efficient foundations that are able to carry higher load, leading to less excavation...

The London Geotechnical Centrifuge Centre at City University London

The London Geotechnical Centrifuge Centre located at City University, London is one of four currently active centrifuges in the UK. The centrifuge is well used and much of the geotechnical research at City University employs physical modelling but supported by a large element testing facility and numerical modelling capability. The centre was...
