提出了一种基于损伤力学理论和小波分析的非连续岩体识别方法。基于确定性方法的参数识别方法分为逆方法和直接方法。该方法结合了逆方法和直接方法，并通过应用离散小波变换的迭代方程的系统矩阵，我们估计未知的损伤张量的情况下，未知参数的数量超过了观测数据。该方法的有效性进行了检查岩土工程问题。版权所有© 2009约翰威利父子有限公司。
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 © 2009 John Wiley & Sons, Ltd.
