Experimental study on relationship between surface temperature and volumetric strain of rock under uniaxial compression
Abstract：A series of surface temperature variation laws of various rock under uniaxial were measured by far-infrared image instrument. Several corresponding volumetric strain of rock samples were measured by strain gauge. Based on the measurement results, the relationship between surface temperature and volumetric strain of rock samples during the compression process was obtained. The experiment results show that rock infrared radiation temperature, in most de- formation process of rock under compression, increases with the rising load, and increase with the increases of the com- pressive volumetric strain, and the latter is more in line with the thermodynamics. The research results can be used to reveal a theoretical relationship between temperature of rock and strain or stress.
