Abstract:Commercially available total earth pressure cells and gaging systems are investigated. The principles of operation for nine commercially available pressure cells are presented, and the manufacturers performance ratings are summarized. The performance characteristics of four types of pressure cells selected for this preliminary study are determined by lab calibration. The four pressure cells selected include the Geonor vibrating wire, Carlson unbonded strain gage, Terra-Tee pneumatic, and Gloetzl hydraulic types.
