为研究含水粉砂岩破裂过程中红外辐射温度变化对应力的敏感程度,采用实验与数据分析的方法,对粉砂岩单轴加载红外辐射温度进行分析.研究结果表明:水对粉砂岩破裂红外辐射敏感性影响较大,且存在一个临界转换点(质量分数1.464%).当质量分数MF<1.464%时,质量分数增大“红外辐射-应力”的敏感性增强;反之,敏感性减弱.另外,MF=2.563%是水对红外辐射温度变幅影响的一个关键点.低于2.563%时,质量分数增大红外辐射温度降幅增大;反之,红外辐射温度降幅减小.
In order to study the sensitivity of infrared radiation temperature to the stress in rupture process of siltstone, the uniaxial infrared radiation temperature of silty sandstone was analyzed by means of experiment and data analysis.The results show that water is sensitive to ruptured infrared radiation of siltstone The sexual influence is larger, and there is a critical transition point (mass fraction 1.464%) .When mass fraction MF <1.464%, the sensitivity of mass fraction increase “IR radiation-stress” is enhanced; on the contrary, the sensitivity is weakened. In addition, MF = 2.563% is one of the key points of influence of water on temperature variation of infrared radiation, and when it is lower than 2.563%, the decrease of temperature of infrared radiation increases with the increase of mass fraction; on the contrary, the decrease of infrared radiation temperature decreases.
