Description

technical field [0001] The present application generally relates to the technical field of rock mechanics characteristics, and specifically discloses a real-time air temperature uniaxial compression experiment device, system and method. Background technique [0002] High geothermal heat is one of the main adverse geological hazards faced by deep-buried tunnel engineering. After the surrounding rock is excavated, the high-temperature rock mass is exposed to extremely low temperatures. The impact of the high temperature difference on the physical and mechanical behavior of the surrounding rock and supporting structures is still unclear. . In addition, the freeze-thaw cycle after excavation will also cause the deterioration of the mechanical properties of the tunnel surrounding rock. Therefore, it is of great significance to study the influence of real-time temperature changes on rock damage characteristics under uniaxial pressure for the construction and construction of deep ...
