GeoCentrifuge

GS_DELTARE_GC-54_736x190_acf_cropped
The GeoCentrifuge is used to simulate processes to scale that can take months in reality. This is done by applying high gravitational forces, which represents a acceleration in time for the processes involved in geo-engineering. The centrifuge also films and measures phenomena in the ground in a way that would not be possible in practice. All the tests are developed specifically. Various alternatives can be compared quickly.

The Deltares GeoCentrifuge stands out from others in that it combines the maximum level of G‑forces (300), the dimensions of the container in which the research is located (2 m3) and, of course, the expertise and skills of our technicians. In addition, Deltares has a digital development environment that converts and validates the measurement data to produce numerical models. That makes possible a very wide range of testing. The results and the video images can be viewed live on the Internet.

The Deltares GeoCentrifuge is available for commercial purposes and it is used for assignments from clients including government authorities, engineering companies, oil companies and the offshore industry, as well as groups of smaller market players. In addition, the facility is used for scientific research.

Examples of recent tests are:

  • Dikes on Peat – a validation experiment looking at the failure behaviour of clay dikes on a peat subsurface
  • Pile foundations – Research looking at ageing and group effects
  • Anchor pulling experiments – Cables and lines on or just under the seabed can be damaged by dragging anchors. Research leads to new design models that reduce the probability of damage.

Dimensions and figures:

  • Maximum G-forces: 300
  • Container dimensions: 2x1x1 m3
  • Weight of container: 2 tonnes
  • Maximum weight of model: 3.5 tonnes
  • Length of arm: 5.5 metres
  • Drive: 2 motors, 200 kW each
  • Maximum speed: 456 km/h
  • Maximum revolutions: 3.7 per second
