Evaluating criterion of relative strength-weakness characteristic based on acoustic emission parameters of rockmass stability

Based on the test results of acoustic emission parameters in laboratory and on site, evaluating criterion of relative strength-weakness characteristic based on the acoustic emission parameters of rockmass stability is presented. Not only the acoustic emission patameters in failure process are considered, but also the evaluating criterion are dealed with in standard. Then, the effect of the environmental factors are eliminated. So, the evaluating criterion of rockmass stability are more effective.
