Abstract

METHODS OF STUDYING OF SELECTED ROCKS IN POLAND UNDER CONDITIONS OF HIGH PRESSURE AND TEMPERATUREAbstract. The study presents methodology for rock testing in conventional triaxial conditions with simultaneous recording of longitudinal wave speed velocity. Assembled at Department of Geomechanics of Warsaw University, the testing unit consists of a rigid strength press equipped with thermal pressure vessel and ultrasonic measuring system. Testing set is able to records automatically the changes of stress, strain and longitudinal wave velocity during strength test conducted in the thermal pressure vessel. Described methodology allows comparing obtained data with in situ geophysical investigations.
