pressure cell for geotechnical test

Total pressure cells measure the combined pressure of effective stress and pore-water pressure. In general, pressure cells are used to verify design assumptions and to warn of soil pressures in excess of those a structure is designed to withstand. Typical applications include:

Determining the distribution, magnitude, and directions of total stresses in an embankment or in the clay core of a dam.
Confirm that tailings material is densifying at design rate.
Estimate overburden pressure acting on foundation.
Measure contact pressures in abutments and foundations.
Measure stress fields in shotcrete.
