Study on infrared radiation characteristics of layered gneiss
In order to explore the rupture instability and infrared radiation temperature field evolution characteristics of different bedding dip gneisses,and to capture the precursor information of rock instability,uniaxial compression tests were carried out on five types of bedding dip gneiss.The results sh...

| description | In order to explore the rupture instability and infrared radiation temperature field evolution characteristics of different bedding dip gneisses,and to capture the precursor information of rock instability,uniaxial compression tests were carried out on five types of bedding dip gneiss.The results showed that,with the increase of bedding dip angle,the peak strength showed a trend of first decreasing and then increasing.The bedding structure effect of the peak strength of gneiss at 60°was the most obvious.Under the same inclination angles,the temperature field changed from uniform to concentrated distribution with the increase of stress.Under the same stress,the larger the inclination angle was,the sooner the concentrated distribution of high temperature bands could be observed.Fractal dimension,entropy and variance could effectively express the evolution processes of infrared radiation temperature field at the same inclination and different stress.The fractal dimension decreased as the energy released by the r |
