Abstract

U diplomskom radu je ispitivana hidraulička vodljivost dolomitnog grusa s područja Žumberka na permeametru sa stalnom razinom. Dolomitni grus se nalazi u rasjednim zonama u različitim mjerilima u području Žumberka te je posebno zanimljiv s hidrogeološkog stajališta. Ukupno 5 uzoraka je prikupljeno terenskim radom, a u laboratoriju je uz mjerenja permeametrom napravljena i granulometrijska analiza tih uzoraka. Rezultati dobiveni mjerenjima u permeametru su uspoređeni s rezultatima dobivenim pomoću empirijskih formula. Pomoću rezultata ispitivanja su dobiveni Reynoldsovi brojevi 𝑅𝑒 na temelju kojih se može pretpostaviti laminaran ili turbulentan tok. Obratila se posebna pozornost na veličine Reynoldsovog broja kao i na valjanost Darcyeva zakona.

Abstract (english)

In this master's thesis is tested hydraulic conductivity of dolomite grus (sand to gravel size particles resulting from tectonic crushing and weathering of dolomites) from the Žumberak area using Constant Head Permeability Test Method. Dolomite grus is located in fault zones in Žumberak area and it's very interesting from the hydrogeological stand. Constant Head Permeability Test Method was conduceted on five samples from five placemarks. Also, granulometric analysisareconducetd on all tested samples. Results from the Constant Head Permeability Test are compared with those obtained from empirical equations. Reynolds numbers are obtained from the results of permeability method and those numbers are telling is it laminar or turbulent flow. Special attention is dedicated on sizes of Reynolds numbers and Darcy law validity.
