摘　　要：基于室内声发射实验和现场岩体稳定性声发射测试参数,提出了评价地下工程岩体稳定性的声发射相对强弱指标,该指标综合考虑了岩体失稳过程的声发射参数,可消除声发射测试参数受工程布置和地质构造等环境因素的影响,能更有效地进行围岩稳定性评价。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 dealt with in standard. Then, the effect of the environmental factors are eliminated. So, the evaluating criterion of rockmass stability are more effective.
