Abstract:
Acoustic emission (AE) phenomenon will occur during the production and propagation of internal cracks, and failure in brittle rock. Under uniaxial loading, the complete stress-strain curves and waveform data were obtained. The Welch spectrum estimation and Cubic spline interpolation method were used to analyze the evolution of F, R values (peak frequency, energy percentage) of AE. The results show that F-values are maintained at 100±20kHz, and the peak points of F and R above 25% which can be used as a precursor to rock failure that their waveform are burst-type. The combined analysis of stress and F, R supplies a more accurately method of predicting the occurrence of rock burst. © (2013) Trans Tech Publications, Switzerland.

我的773檢索了，可是到現(xiàn)在沒(méi)有收到論文集，會(huì)友們，你們收到了木有？難道會(huì)務(wù)組為了省錢(qián)不給我們。我們年度考核要查看原文呀，么辦呢？
