Geo Model Laboratory
We have a large and small container (measuring 4 x 2.5 x 1.2 m (lxwxh) and 2 x 1 x 1.1 respectively), cell rings (with diameters of 0.3 m, 0.6 m, 0.9 m and 1.25 m), a large triaxial cell (sample size of 0.85 m and a diameter from 0.45 m) and climate chambers for temperature-controlled experiments. A wide range of pressure and strain gauges, cones and probes are available for monitoring, in conjunction with a 3D surface scanner.
Tests in these arrays make it possible to determine, in conditioned circumstances, the static and dynamic properties of soil and soil-structure interaction and to validate and optimise geotechnical designs using the results. The experiments are also used to devise and validate models and design rules.
In addition, we have a number of unique arrays that are used for more fundamental research looking at the failure mechanism of piping, and at hybrid structures for piled embankments.
Examples of recent tests are:
- Asphalt revetment studies for dikes
- Deformation study of underground lines
- Validation tests for domestic gas mains connections
- Large-diameter triaxial tests looking at ores, coarse-grained materials and peat
- Calibration studies for piezometers
- Piping tests and tests for counter-piping measures.
