Project

Subject and tasks: definition of the state and properties of rock masses, geomechanical characteristics of rocks and soil, hydrogeological characteristics issued on the metro route, and based on which the geotechnical conditions and recommendations for the construction of the future metro line will be defined at the conceptual project level. Preparation of the Elaborate was preceded by field work and laboratory tests of soil and rock samples. The field work included exploratory drilling, mapping of drilled cores, taking water, soil and rock samples, SPT, CPT tests, pouring tests and geophysical measurements in boreholes (down hole test) and measurements on the surface of the field, which were completed (June 2021). On the route of the first phase of the first Line of the Belgrade Metro, 123 exploratory wells with a total depth of 4231 meters were drilled. The laboratory tests that were carried out in the geomechanical laboratory of the "Institute for Mining and Metallurgy Bor" and the "Mining Institute"-Zemun included tests on rock and soil samples (swelling, point load test, uniaxial strength, triaxial tests, abrasiveness, etc.) and were completed (July 2021). The Elaborate in question was prepared by the Consortium: Hidrozavod DTD, Institute for Mining and Metallurgy Bor, Mining Institute-Zemun, Geomag doo, Geoing Group (November 2021).
