摘要：

This paper presents an identification method using observational boundary conditions and discrete wavelet analysis. The material parameter identification methods which belong to deterministic approaches are classified into inverse and direct approaches. The proposed method combines the inverse approach and the direct approach [1, 2], and by applying the discrete wavelet transform to the system matrix of the iteration equation, we estimate unknown elastic constants and damage tensors of jointed rock masses for the cases in which the number of unknown parameters exceed the observed data. Layered vertical slope examples are calculated to investigate the validity of the method.
