Abstract
Na području strojarnice HE Dubrava izveden je pokusno-eksploatacijski zdenac B-3 kojim je zahvaćen drugi vodonosnik izgrađen pretežno od šljunaka i pijesaka. Također je izvedeno i devet piezometarskih bušotina. Pokusno crpljenje zdenca B-3 provedeno je u tri koraka, s promjenjivom crpnom količinom (step test). U ovom radu opisan je postupak step testa zdenca B-3 i određene su vrijednosti hidrauličkih karakteristika zdenca na temelju podataka step testa. Za interpretaciju podataka step testa korištena je Jacobova metoda. Pomoću Jacobove metode izračunate su vrijednosti koeficijenata u Jacobovoj jednadžbi ukupnog sniženja u zdencu tako da koeficijent linearnih gubitaka B iznosi 11,479 s/m2, a koeficijent nelinearnih gubitaka C iznosi 71,727 s2/m5. Također su određeni specifični kapacitet i efikasnost zdenca B-3.
Abstract (english)
At the location of the power station HPP Dubrava, a test-exploitation well B-3 was constructed, which affected the second aquifer that was built mainly of gravel and sand. Nine piezometric wells were also drilled. Experimental pumping of the well B-3 was carried out in three steps including, a variable pumping quantity (step test). In this paper, the step test procedure test of the well B-3 is described and the values of hydraulic characteristics of the well were determined based on the step test data and for their the interpretation Jacob's method was used. Using Jacob's method, the values of the coefficients in Jacob's equation of total reduction in the well were calculated so that the coefficient of linear losses B was 11,479 s/m2, and the coefficient of nonlinear losses C was 71,727 s2 / m5. The specific capacity and efficiency of the well B-3 were also determined.
