A TRIAXIAL PRESSURE APPARATUS FOR TESTING OF CONSOLIDATED OR UNCONSOLIDATED MATERIALS SUBJECTED TO PORE PRESSURE

TO DETERMINE THE EFFECTS OF DIFFERENT STRESS STATES AND PORE PRESSURE ON THE COMPACTION OF SEDIMENT AND ON THE DEFORMATIONAL BEHAVIOR OF ROCK, A TRIAXIAL APPARATUS WAS DEVELOPED THAT PERMITS CONTROL OF PORE PRESSURE DURING TRIAXIAL TESTING OF MATERIALS UNDER HIGH CONFINING PRESSURE. THE APPARATUS IS DESIGNED FOR USE WITH 1-IN. DIAMETER BY 2-IN. LENGTH SPECIMENS SUBJECTED TO CONFINING PRESSURES AND PORE PRESSURES UP TO 30,000 PSI AND AXIAL STRESS UP TO 130,000 PSI. THE AXIAL LOAD CAN BE HELD CONSTANT OR VARIED CONTINUOUSLY DURING TESTING. THE COMPACT NATURE OF THE APPARATUS PERMITS MOBILITY THAT MAKES THE APPARATUS PARTICULARLY DESIRABLE WHERE FIELD TESTING IS NECESSARY. /AUTHOR/
