摘要： 为了研究含水率对岩石红外辐射信息的影响，对4 种不同含水率的岩样进行单轴压缩试验，并同步进行红外
辐射观测。研究结果表明，随着岩样被不断压缩，红外辐射计数的变异系数逐渐增大，承载岩样的损伤程度逐渐增大。
对比不同含水率承载岩样的各个阶段发现，随着含水率的增加，各个阶段的红外辐射计数变异系数逐渐增大，承载岩样
的损伤演化程度逐渐降低。岩样各个加载阶段，随着含水率的增加，红外辐射计数率呈上升趋势。含水使得岩样各个加
载阶段损伤演化程度上升，加载全过程红外辐射计数随含水率的增大而增大。

Abstract: In order to study the influence of water content on the infrared radiation information of rocks, this paper performed
uniaxial compression experiments on 4 kinds of rock samples with different water content, and performed infrared radiation observations
simultaneously. The research results showed that as the rock sample was continuously compressed, the infrared radiation
variation coefficient counts gradually increased, and the damage degree of the bearing rock sample gradually increased. Comparing
the various stages of bearing rock samples with different water content, it was found that with the increase of water content, the
coefficient of infrared radiation counts of rock samples in each stage gradually increased, and the degree of damage evolution of
bearing rock samples gradually increased. The water content reduced the damage evolution of the rock samples during each
loading stage, and the infrared radiation count during the whole loading process increases with the increase of the water content.

Key words: infrared radiation; uniaxial compression; water-bearing coal rock; variation coefficient
