Summary: | The invention discloses an on-site servo controlled actual triaxial testing apparatus for rock mass. The apparatus comprises an axial pressure loading system, a confining pressure loading system and a measurement and acquisition control system. A technical scheme for the invention is mainly as follows: a steel plate is horizontally arranged on the top of an on-site columnar rock sample in an underground grotto; at least two or more uniformly distributed jacks are arranged on the steel plate; steel plates are horizontally arranged on each jack; force transmission columns are arranged on the steel plates; steel plates are horizontally arranged on the force transmission columns and abut against the rock surface in the underground grotto; the columnar rock sample has a length in a range of 30 cm to 100 cm, a width in a range of 30 cm to 100 cm and a height in a range of 60 cm to 150 cm; one end of a measuring rod is arranged in the center of the top of the columnar rock sample, and the other end of the measuring |
