Abstract: Acoustic emission monitoring of the acoustic emission monitoring of the stability of large intrusions covers a large scope of area. Not only the involving geologic framework is complicated, the monitoring is also conducted in a noisy environment with a long period. Therefore, a scientific authentication of how to deal with each part of the acoustic emission monitoring of the stability of large rock mass is the safeguard of effective acoustic emission monitoring. The results in the acoustic emission monitoring of the stability of permanent navigation locks side slope in the Three Gorges were reviewed and stated three important parts in the acoustic emission monitoring— feasibility analysis on the acoustic emission monitoring of the stability of large intrusions, the design principles of acoustic emission monitoring of the stability of large rock mass, and the stability analysis of large rock mass. They were not only the important achievements from the research in the acoustic emission stability monitoring of the stability of large rock mass, but also served as good references for the reliability of the acoustic emission monitoring of the stability of large rock mass.
