Description
The GEOTEST is a highly advanced rock triaxial testing apparatus that excels in conducting triaxial tests, creep tests, and post-failure behavior evaluations. This versatile system can determine a wide range of geomechanical properties under triaxial compression conditions, including rock deformation properties, rock compressive strength, and static elastic constants. Additionally, it offers optional fixtures to expand its capabilities, enabling the performance of unconfined compressive strength tests, indirect tensile strength tests, acoustic velocity measurements, dynamic elastic constants assessments, rock permeability evaluations, rock compressibility assessments, polyaxial compression tests, hydraulic fracturing experiments, and acoustic emission tests. The hydraulic compression frame applies axial loads to a sample securely mounted in a balanced triaxial cell. This system accommodates both static and cyclic tests. Its stress-testing capabilities are virtually limitless within the device's physical constraints, and experiments can be conducted under stress feedback, strain control, or manual operation. To enhance specimen loading speed and overall system efficiency, it incorporates an integrated hydraulic cell setup mechanism. This mechanism involves mounting and instrumenting the sample on the cell pedestal, lowering the cell body, securely locking it against the pedestal, and then positioning it under the piston loading area.
