针对裂隙岩体的非均质性、各向异性特点,本次毕业设计对紫坪铺水利枢纽工程地下洞室开挖后洞壁裂隙结构面进行了几何参数测量和分组,再利用渗透量理论计算各测量洞段渗透量值,获得裂隙介质三维渗透量场。

First, a non-negative tensor factorization algorithm is improved by imposing sparseness constraints on it. Secondly, the bispectral images of mechanical signals are obtained and stacked to form a third-order tensor. Thirdly, the improved algorithm is used to extract features, which are represented by a series of basis images from this tensor. Finally, coefficients indicating these basis images' weights in constituting original bispectral images are calculated for fault classification.
