Abstract In order to explore abnormality of infrared temperature field(ITF) in the process of rock cracking and destabilization，the concept of infrared temperature variation field(ITVF) was put forward in the paper，and the transient characteristics of ITF during rock failure was analyzed and discussed based on the experiment on saturated siltstone samples under thermal imaging observation in loading process. A certain abnormal phenomenon of ITVF during rock instability was found. The abnormal jump of ITVF characteristic parameters，including Range(R)，Kurtosis(K)，Mutation Ratio(MR)，etc，exists in the failure process of saturated siltstone. The occurrence probability of anomalies was up to 88.8%，mainly in the plastic and post-peaking phase，especially tending to appear at the moment of marked pressure dropping. When the deformation entered into the plastic and post-peaking phase，ITF jumped due to the intensified development of specimen surface fracture and the infrared temperature variation rate moved to the direction of the maximum or minimum，which resulted in the abnormal jump of R and the sudden increase in the number of ITVF abnormal value，thus caused K and MR a sudden jump. The ITF anomalies generally exist in the process of ductile fracturing of rock.
