  • INNER AND OUTER FRAMEWORK COMBINED VARIABLE STIFFNESS ROCK MECHANICS TESTER AND TESTING METHOD
    Publication number: 20210223152
    Abstract: The present disclosure provides an inner and outer framework combined variable stiffness rock mechanics tester and a testing method, relating to the technical field of rock mechanics. The tester includes a stiffness adjusting apparatus, a test loading apparatus, a monitoring system, and a control system. During a test, according to monitoring data, the load of the stiffness adjusting cylinder is controlled through the control system, and the displacement of the inner top beam is adjusted in real time, to ensure that the loading stiffness reaches a design value and remains constant, which solves the technical problem that the loading stiffness of the rock mechanics tester cannot be quantitatively adjusted, and is easy to operate.
