单向压缩下岩石表面温度与体积应变关系实验
|
摘要
在单向压缩条件下,通过远红外热像仪,测得了多种岩石试件表面温度随载荷的变化规律,通过贴于试件表面的应变片,同时实测了试件总体的体积应变值,据此寻找岩石试件在受压过程中,试件表面温度与体积应变之间的关系。研究结果表明,在岩石受压的大部分变形过程中,岩石红外辐射温度会随载荷的增加而增加,也随着压缩体积应变的增加而增加,后一结论比较符合热力学定理的预示。实验结果有助于将温度变化与应力或应变变化定量联系起来。
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 deformation process of rock under compression,increases with the rising load,and increase with the increases of the compressive 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.
