Slide disaster forcast is a worldwide difficulty problem,Earthquake belongs to losing-balance of non-line system,and slide as well.Identification and extraction of earthquake auspice information as the main basis of earthquake happened time and earthquake grade forcast.It is difficulty to observe the abnormal characteristic of rock distortion slope evolvement signal using the eye and traditional method.Wavelet analysis as the better mathematics implement with the better time and sequence analysis ability applies in identification of slope evolvement.And getting the good engineering result.It proves that wavelet analysis in the auspice abnormality extraction of the rock distortion the slope evolvement is feasible and effective.
