摘要：
This paper presents an identification method for a discontinuous rock mass employing damage mechanics theory and wavelet analysis. Parameter identification methods based on deterministic approaches are classified into inverse and direct approaches. The proposed method combines the inverse approach and the direct approach and by applying the discrete wavelet transform to the system matrix of the iteration equation, we estimate unknown damage tensors for the case in which the number of unknown parameters exceeds the observed data. The validity of this method is examined for geotechnical engineering problems. Copyright (C) 2009 John Wiley & Sons, Ltd.
