In this research paper, a new method is developed that can be used as a precursor of violent rock failure. It is based on measuring the characteristics of rock failure using infrared radiation (IR) under uniaxial cyclic loading and unloading. The loading–unloading response ratio (LURR) is determined based on IR indexes such as average infrared radiation temperature (AIRT) and infrared radiation temperature rate (IRTR). The results show that the LURR based on AIRT revealed an overall rising trend and mutation that occurred in the last cycle, which can be used as a precursor of the imminent rock failure. By contrast, the LURR based on IRTR has a noticeable ‘mutation‐rapid decrease’ in the middle and later periods of cyclic loading and unloading, which can also be considered as an early precursor of rock failure. Combined with the precursors of the imminent rock failure, the categorized warning of rock failure is recognized.

使用红外辐射作为剧烈破坏的先兆，岩石破坏的循环疲劳特性：来自加载和卸载响应的实验见解

在这篇研究论文中，开发了一种新方法，可以用作猛烈岩石破坏的先兆。它基于在单轴循环加载和卸载条件下使用红外辐射（IR）测量岩石破坏的特征。装卸响应比（LURR）是根据IR指数（例如平均红外辐射温度（AIRT）和红外辐射温度速率（IRTR））确定的。结果表明，基于AIRT的LURR揭示了在最后一个周期中发生的总体上升趋势和突变，可以用作即将发生的岩石破坏的先兆。相比之下，基于IRTR的LURR在循环加载和卸载的中期和后期具有明显的“突变快速降低”，这也可以视为岩石破坏的早期先兆。
