| Abstract | Firstly, acoustic emission tests of rock under uniaxial compression are carried out. Secondly, frequency spectrum characteristics and its distribution regularity are obtained by specimens tests. Subsequently, Db4 series wavelet base is choosed to denoise rock AE data and results show that the method is simple and effective. Thirdly, it was found that at Kaiser point the energy percentage of dominant frequency band is significantly higher than other points, and the value of relevant fractal dimension is minimum. Furthermore, Kaiser effect of AE will appears when ultrasonic velocity declines obviously according to the discussion of the relationship between ultrasonic velocity and AE. |
