Research and Analysis on rock Acoustic Emission wave characteristics JianPing He1, a 1Dept. of civil Engineering of Luoyang Institute of Science and Technology,Luoyang,471023,China ahejp1348@163.com Keywords: rock mass,AE,wave characteristics Abstract.
AE signal waveform analysis Acoustic emission sampling points is 1024 for the original signal, which lasted 411. according to the formula of (1), (2) ,the original AE signal decomposition layer 5,to obtained the approximate signal (frequency signal) and the detail signal (high frequency signal) in Figure 3,4.Engineering practice, the useful signal manifests itself in the low-frequency signal or some of the more stable signal, and the signal is manifested in the high-frequency noise signal; acoustic emission signal (useful signal) reflected in part the approximate signal and noise signal (unwanted signals) is reflected in details of the signal section; approximation signal clearly shows acoustic emission of the steady rock is a relatively stationary random signal indicating that the state of rock no new damage internal expansion, rock pressure not exceeding the rocks the ultimate bearing capacity, acoustic emission main frequency is the lower frequency, which is consistent with the statistical
