THE INFLUENCE OF DIAPHRAGM FLEXIBILITY ON THE PERFORMANCE OF AN EARTH PRESSURE CELL

A THEORETICAL ANALYSIS OF THE EFFECT OF A FLEXIBLE DIAPHRAGM ON THE CALIBRATION OF A PRESSURE CELL SUBJECTED TO ONE DIMENSIONAL COMPRESSION IS PRESENTED TOGETHER WITH THE RESULTS PREDICTED FOR A RANGE OF CELL THICKNESS TO DIAMETER RATIOS, IN SOILS OF DIFFERENT MODULI. THE LIKELY OVER OR UNDER REGISTRATION OF A CELL IN A GIVEN SOIL CAN BE READILY OBTAINED AND, MORE IMPORTANT, THE PROBABLE SENSITIVITY OF THE CALIBRATION OF THE CELL TO THE SOIL MODULUS IS EASILY SEEN. THE RESULTS ARE RESTRICTED TO A CELL HAVING AN ACTIVE DIAMETER TO OVERALL DIAMETER RATIO OF 0.6, A FAIRLY TYPICAL VALUE. /AUTHOR/
