Several 1-g model testing facilities are available at GeoDelft.
Large testing container surnamed'Bak-van-Smits'(dim. 4m x 2.5mx 1.5m) has been constructed with a nozzle network on the bottom. Through these nozzles water can be injected with high pressures breaking the compacity of the sand block. Sand gets fluidized. Mounted steel grids can be used to densify the sand model. By this technique saturated sand models can be prepared with a wanted relative density of loose to dense (Dr(n)~80%). Capillary sand can also be prepared.
Testing domains: (cone) penetration tests, testing of field push-away techniques, compaction tests, trench tests, etc.
Medium testing container surnamed 'Brutusbak' (dim. 2m x 1m x1m). The 'Brutusbak' is provided with two parallel glass window making possible visual observations along the sand model profile. It has the same fluidization system as the large testing container. Sand models is compacted using shock waves. Obtained sand densities vary from loose to dense (Dr(n)~80%).
Testing domains: Soil deformations around a vibrating sheet-pile, arching effects, scaled geocontainers, etc.
