Construction of anti-seepage curtains during jet mining

Abstract

Abstract. The Rock Mass and artificial constructions, during the changes of the stress-strain conditions are involved in specific types of interactions. The case explained in the article is a very specific, having in mind the closely spaced arch dam and existing intake tunnel. In order to insure the data for analyses, it is necessary to define the reliable constitutional model or analyses. According to the authors opinion, the combination of discontinual Rock Mass models and models for analyzing of quasi-continual media is a prerequisite for successful design and construction.
