摘要：
This paper deals with the prediction of disaster in rock engineering with an acoustic emission technique. Variations of acoustic emission signals have been detected on the specimens from two dam areas in the process of rock fracture, and the relationship between these variations has been investigated. The results show that it is possible to detect and predict the unstable tendency of surrounding rocks, slide and collapse on the bases of their roles of acoustic emission in the process of rock deformation and damage. Though there are some difficulties in using this method in situ, no doubt, this method is one of hopeful means to predict the occurrence of disaster, and is worth researching further.
