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.
Highlights
The arch dam Matka on a river Treska in R.Macedonia is one of the oldest constructions in a Balkan region, constructed during the beginning of 20 century after First World War. (Fig. 1) It is still an example of well designed and constructed object

Summary
The arch dam Matka on a river Treska in R.Macedonia is one of the oldest constructions in a Balkan region, constructed during the beginning of 20 century after First World War. (Fig. 1) It is still an example of well designed and constructed object. The design of larger surge tank is necessary, which means that new excavations shall be prepared very close to the slope surface, as well as to the zone of arch dam. Having in mind the specific surroundings, the main goal of this analysis is to introduce adequate methodology for excavation of surge tank enlargement of HEC MATKA1. In this analysis information’s from the geological, geophysical and geotechnical investigations are used, and additional, some specific structural measurements are prepared in order to collect data about the joint set properties and orientation [1,2,3,4].
