MDS and IDW transform for image processing of hydrogeological structure in rock mass

Abstract

A novel imaging method for the establishment of hydrogeological model of rock mass is proposed. The hydraulic data set of cross-hole test, which represents hydraulic property of in situ rock mass, is processed to evaluate a spatial distribution of hydraulic property by the multidimensional scaling (MDS) and the inverse distance weighted (IDW) interpolation. The reliability of this method is validated by numerical experiments using several continuum models with different hydraulic structures, and the applicability of the method is also examined by the field experiments.
