EVALUATION OF PRESSURE CELLS USED FOR FIELD MEASUREMENTS OF LATERAL EARTH PRESSURES ON RETAINING WALLS

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-TEC PNEUMATIC, AND GLOETZL HYDRAULIC TYPES. INSTALLATION OF THE FOUR TYPES OF PRESSURE CELLS IN A CANTILEVER RETAINING WALL IS DESCRIBED. WALL MOVEMENT AND MEASURED EARTH PRESSURES ARE PRESENTED GRAPHICALLY. THEORETICAL EARTH PRESSURES ON THE INSTRUMENTED RETAINING WALL ARE DETERMINED BY THE RANKINE AND COULOMB THEORIES AND A COMPARISON IS MADE WITH THE MEASURED LATERAL EARTH PRESSURES. THE RELATIVE MERITS OF EACH CELL IS SUMMARIZED AND PROBLEM AREAS ARE IDENTIFIED. /AUTHOR/
