  • Geotehnički uslovi izgradnje metro stanice „Savski trg“ – beogradski metro linija 1

    Dragoslav Rakić, Nemanja Stanić, Josip Išek, Slavoljub Stojković (2023)
    Ukrštanje linija 1 i 2 beogradskog metroa, planirano je na lokaciji “Savski trg” gde će se izgraditi zajednička metro stanica. Zbog složene konstrukcije objekta i različite dubine dijafragmi, koja na delu metro linije 2 iznosi preko 40 m, planirana je fazna izgradnja. U vezi sa tim u radu je prikazan način definisanja geotehničkog modela, kao i geotehnički proračuni u kojima su analizirani: fazni načini iskopa, filtraciona analiza, uticaj pornih i efektivnih napona na stabilnost dijafragme, horizontalna i vertikalna ...

  • A Model for Determining Fuzzy Evaluations of Partial Indicators of Availability for High-Capacity Continuous Systems at Coal Open Pits Using a Neuro-Fuzzy Inference System

    Miljan Gomilanović, Miloš Tanasijević, Saša Stepanović, Filip Miletić (2023)
    This paper presents a model for determining fuzzy evaluations of partial indicators of the availability of continuous systems at coal open pits using a neuro-fuzzy inference system. The system itself is a combination of fuzzy logic and artificial neural networks. The system availability is divided into partial indicators. By combining the fuzzy logic and artificial neural networks, a model is obtained that has the ability to learn and uses expert judgment for that learning. This paper deals with the ...

  • Hidrogeološke karakteristike i ocena bilansa Ravaničkih krečnjaka

    Andrijana Stanišić (2024)
    Hidrogeološka problematika koja se vezuje za složene uslove cirkulacije podzemnih voda u karstu kao i kompleksnost karakterizacije karstnih izdanskih voda, predstavljaju ključne faktore za usmeravanje ka istraživanju karsta i definisanje teme završnog rada. Tematikom rada obuhvaćene su prvenstveno hidrogeološke karakteristike područja istraživanja a zatim i analiza elemenata režima i bilansa podzemnih vodnih resursa u cilju njihove pravilne valorizacije.Zapadni krečnjački pojas Karpato-balkanskog luka odvojen je od mezozojskog kompleksa Kučajsko-beljaničkog masiva navlakom crvenih permskih peščara, koja se nastavlja na krepoljinsko-senjsku zonu ...

    Lamprofiri su grupa egzotičnih ultrakalijskih stena poznatih po sadrţaju nekompatibilnih elemenata i elemenata retkih zemalja. U našem delu sveta pojavljuju se u okviru ultrakalijskih provincija u Španiji, Italiji, Srbiji, Makedoniji i Turskoj. U Srbiji su zastupljeni ponajviše u zapadnim delovima zemlje, oko opština Ljubovija i Mali Zvornik, ali i u široj okolini Rudnika, Kopaonika i u istočnoj Srbiji. Mnoga ispitivanja sprovedena su u rudnom polju Veliki Majdan u zapadnoj Srbiji sa čije jugoistočne strane protiče Kolarička reka. Ovaj lokalitet ...
