Rock triaxial compressive strength tester for determining the strength and deformation
Application:
Method of determining the strength and deformation of specimens under triaxial axial pressure during triaxial compressive strength testing of rocks. Calculation of strength and deformation parameters of specimens under triaxial compression conditions. It also determines the compressive shear strength and Poisson's ratio of the rock. Usually, the triaxial compressive strength test without consolidation drainage and pore water pressure measurement under lateral pressure conditions is used.
Experimental procedure: Firstly, the prepared rock specimen is placed in the triaxial pressure chamber with oil-proof latex sleeve, so that the rock specimen bearing block and ball seat are centered, and then the triaxial pressure chamber is placed on the pressure tester, so that the pressure chamber is centered with the bearing plate. The lateral pressure (circumferential pressure) and axial pressure are applied simultaneously at a loading rate of 0.05mm/min to the preset lateral pressure value, and the lateral circumferential pressure is kept constant, and then the axial pressure is loaded at a loading rate of 0.5MPa~6MPa per second until the specimen is damaged, and the axial load and deformation values are recorded during the test.
Main components: hydraulic axial pressure loading device, three-axis pressure chamber with high pressure resistance of 90MPa, perimeter pressure loading device, computer acquisition and control instrument and analysis system.
