摘要: 大型岩体稳定性AE监测作业范围大, 地质结构复杂, 周期性长, 环境嘈杂, 科学认证、正确处理大型岩体稳定性AE监测中的每个环节是监测工作有效和可靠的保障。以三峡永久船闸边坡稳定性AE监测取得的成果, 阐述了永久船闸边坡稳定性声发射(AE)监测方法中的三个重要环节, 即大型岩体稳定性AE监测的可行性分析、大型岩体稳定性AE监测的设计原则、大型岩体的稳定性分析。它们是大型岩体稳定性AE监测方法的重要成果, 对大型岩体稳定性AE监测具有重要的参考价值。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.
