| 摘 要： | 岩体声发射技术是地下工程中监测围岩稳定性的重要手段。根据大量的现场岩体稳定性声发射信号参数,提出了评价地下工程岩体稳定性声发射相对强弱指标,综合考虑了岩体失稳过程的声发射事件率或能率的时间序列,可以消除测点布置方式及地质构造等因素对声发射信号参数的影响,更准确地进行围岩稳定性评价。

| Abstract: | The rock sound emission technique is important means to monitor the stability of wall rock in underground construction. The evaluation of relative strength index of sound emission of rock mass stability in underground construction was put forward. The temporal series of rock sound emission rate or capacity ratio in the process of rock instability was synthetically considered, which can eliminate the influence of the factors of arrangement of measuring points and geological structure to parameters of acoustic emission signal, and accurately conduct estimation of stability of wall rock. |
