    • Abstract
  • In this paper,wavelet transformation is applied to decompose the rock acoustic signal into wavelet components belonging to various frequence channels,and weight spectrum parameters are given after analysing these channel signals. The data processing of rock acoustic signals under uniaxial loading and Brazillian loading shows that there is a good relationship between weight spectrum parameters and stresses.
