The invention relates to the technical field of rock burst experimental devices, and provides high-pressure servo true triaxial rock burst experimental equipment. The high-pressure servo true triaxialrock burst experimental equipment comprises first to sixth loading mechanisms. The first loading mechanism is used for applying a load to a rock to be experimented in a first direction; the second loading mechanism is used for applying a load to the rock to be experimented in a second direction, and the second direction is opposite to the first direction; the third loading mechanism is used for applying a load to the rock to be experimented in a third direction, and the third direction is perpendicular to the first direction; the fourth loading mechanism is used for applying a load to the rock to be experimented in a fourth direction, and the fourth direction is opposite to the third direction; the fifth loading mechanism is used for applying a load to the rock to be experimented in a fifth direction, and the fifth direction is perpendicular to the first direction and the third direction; and the sixth loading mechanism is used for applying a load to the rock to be experimented in a sixth direction, and the sixth direction is opposite to the fifth direction. The six loading mechanisms of the equipment can be independently controlled, so that the rock can be independently loaded indifferent directions.
Description
technical field [0001] The invention relates to the technical field of rockburst experimental devices, in particular to a high-voltage servo true triaxial rockburst experimental device. Background technique [0002] Rockburst is one of the major disasters faced by deep underground engineering. The problem of rockburst has been paid more and more attention by researchers. Scholars at home and abroad have carried out a large number of rockburst experiments and the development of rockburst experimental equipment. In order to reproduce the phenomenon of rockburst in underground engineering more realistically and provide an experimental basis for on-site rockburst early warning, it is necessary to develop high-voltage servo rockburst equipment that can meet the real stress state and stress conversion caused by excavation. [0003] The current rockburst experimental device can only carry out single-side unloading rockburst experiments under the action of static load or dynamic loa...
