Abstract
The present disclosure discloses a rock high-stress high-temperature micro-nano indentation test system, comprising: an X, Y, Z three-direction macroscopic adjustment module, an indentation precision loading module, an indentation test module and an indentation data processing module. The rock high-stress high-temperature micro-nano indentation test system further comprise a two-dimensional horizontal stress loading device, a temperature control device and a vacuum device 13. The rock high-stress high-temperature micro-nano indentation test system provided by the present disclosure has distinctive features of modularity and structuralization, and its test results have high accuracy. The rock high-stress high-temperature micro-nano indentation test system is easy to operate, and provides a theoretical and technical system support for testing the mechanical characteristics of the rock under the high-stress and high-temperature environment in the deep region.
