Geoteko, Hall Effect Local Strain Transducers

GEOTEKO were required to carry out a series of triaxial tests for one of its clients to assess the samples susceptibility to liquefaction. The void ratio is one of the most important factors that affect the liquefacion phenomenon, therefore the exact determination of this parameter is very important for such tests. It is necessary to monitor the samples void ratio changes at each stage of the test.

Using the standard triaxial instrumentation, it was not possible to monitor the geometry of the sample during the filling of the triaxial cell with water and during the saturation stage. Therefore, void ratio changes at these stages were not registered. GEOTEKO decided to use local displacement transducers from GDS Instruments that mount directly on a sample in the triaxial cell.
