The invention provides a rock mechanical testing machine arranged on a rotary table. The rock mechanical testing machine mainly comprises a pedestal, the rotary table, a testing machine base plate, a lower reinforcing plate of a pressure chamber, an upper reinforcing plate of the pressure chamber, the pressure chamber and a servo-cylinder, wherein the rotary table is fixed on the pedestal through screws; the lower surface of the testing machine base plate matches with the rotary table through front edges, so concentric rotation of the testing machine base plate and the rotary table is realized; the lower end of the pressure chamber and the lower reinforcing plate of the pressure chamber are fixedly connected with the testing machine base plate through screws; and the upper end of the pressure chamber and the upper reinforcing plate of the pressure chamber are fixedly connected with the servo-cylinder through screws. The rock mechanical testing machine provided in embodiments of the invention realizes both axial loading and 360-DEG uncovered CT scanning of a rock soil sample. The whole rock mechanical testing machine is arranged on the rotary table, a loading device is separated from the rotary table, and axially loaded load is internal force of the loading device of testing machine for the rotary table; thus, rigidity of the testing machine is guaranteed, rotation precision is realized, and accuracy of testing results is improved.
Description
technical field [0001] The invention relates to the technical field of rock and soil testing machines, in particular to a rock mechanics testing machine placed on a turntable. Background technique [0002] The rock and soil testing machine is a basic scientific test instrument for studying the stress and strain relationship of rock and soil. It is composed of an axial pressure system, a confining pressure system and a temperature control system. The sample force is applied to the sample through the pressure chamber, and at the same time, the upper and lower end surfaces of the sample and the middle of the sample are respectively placed in different temperature environments through the temperature control system, thereby simulating various conditions of the sample at different temperatures. Actual working conditions. However, the traditional geotechnical testing machine is difficult to observe the internal structure of the material, so it is even more impossible to measure t...
