In recent years, it has been recognized that temperature is an important factor that affects the mechanical properties of rock; thereby studies on the mechanical properties of rock under high-temperature circumstances has become a very active research direction in the field of rock mechanics. Since the mechanical properties of wall rock, due to high temperature, tend to deteriorate it results in reduced safety of the structure of rock engineering; both damage and safety assessments, as a result of high temperature, need to be taken of the structure of such rock engineering in order to provide basis for the analyses of both rock engineering reliability and long-term stability of wall rock. Therefore, the strength properties of rock engineering structures under the action of high temperature have become a focus for the engineering community. In addition, due to an ever-growing complexity of geological conditions of current underground engineering, the environment for the rock media of rock engineering often entails extreme conditions such as shock loads. To sum up the foregoing, research on the dynamics of rock under the action of high temperature is not only an important theoretical issue, but also a significant engineering problem.
