中文摘要：

在分析岩质边坡失稳过程中岩体力学性质和声发射产生的微观机理基础上，通过岩石声发射试验和岩质边坡声发射监测实例，研究了岩质边坡声发射特征，提出了岩质边坡失稳破坏的基本力学分类及其声发射的监测预报方法和判据，实现对岩质边坡失稳的预测预报。研究结果表明，边坡破坏前存在一次或多次声发射高峰。应用AE技术可以确定边坡在变形过程中应力集中活跃区；以抗滑力减小为主的岩质边坡，其失稳预报判据为大事件率在15次／min以上，预报时间为几分钟至数小时。以下滑力增大为主的岩质边坡失稳的预报判据为大事件率在26次／min以上，破坏时间为第一次声发射峰值期后的30-45d。

英文摘要：

Based on the analysis of microcosmic mechanism which is caused by rock mass mechanical property and acoustic emission in the course of rock slope failure, and through rock Acoustic Emission trial and monitor example of rock slope Acoustic Emission, the acoustic emission features of rock slope are studied; and the basic mechanical classification of deformation and failure of rock slope and the monitoring-predicting methods and criterion of AE are put Arward, and the forecasting of rock slope failure is implemeted. The research result shows that one or more peak values of acoustic emission appear before the failure of rock slope; the application of AE technology can determine the stress concentration and active areas during the deformation of slide slope; for the rock slope with decreasing ＂sliding resistance force＂, the failure prediction criterion is that the AE major events rate is more than 15 times per minute and the forecast time is from several minutes to hours; for the rock slope with the increasing ＂sliding force＂, the AE major events rate is more than 26 times per minute and the failure will occur in 30 to 45 days after the first peak value of acoustic emission.
