- W2356572099 abstract "The rheological deformation of surrounding soft rock of roadway in deep mine can be caused by perturbation load. In order to establish the constitutive relation of roadway surrounding rock,the testing machine for rock rheological perturbation effect should be developed to conduct experiments. The testing machine is able to apply long-term constant axial pressure and confining pressure and perturbation load,and to test the perturbation load and rock deformation. The developed RRTS-II testing machine for rock rheological perturbation effect,whose axial pressure adopted by gravity loading,is suitable for long-term rheological test. The axial loading is achieved by gear and hydraulic structures;the pressure can reach 100 MPa,which is up to 60-100 times than the gravity loading. The perturbation load applied by impact and blast can be measured by blasting vibration recorder,whose measurement accuracy is 0.015 mm/s. The confining pressure applied by triaxial cell,which is achieved by high pressure gas energy storing device,can reach 10 MPa. The testing machine is equipped with load,displacement,strain and vibration test systems and corresponding data processing software. It is suitable for uniaxial and triaxial compression tests under low confining pressure with perturbation load. Test results show that the testing machine has reasonable structure,stable performance and high precision." @default.
