| Abstract: | Creep is an important mechanical property of rock, which is closely related to the long-term safety, stability and safety of the project. Acoustic emission technology, as a non-destructive testing method, is widely used in the field of rock deformation and failure research. This paper describes the research progress of rock creep characteristics based on acoustic emission technology in recent years, mainly including the acoustic emission characteristics of rock creep under different lithology, loading methods, and stress levels, and the precursor characteristics of acoustic emission of rock creep failure. On this basis, several issues that need to be further studied in the future are put forward. |
