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.
