Abstract

Kontrola podzemne vode nam služi za sprečavanje hidrauličkog sloma, prevelikog uzgona, nemogućnost izvođenja radova u suhom te negativnog utjecaja na građevine. Snižavanjem podzemne vode se smanjuju porni tlakovi te se povećavaju efektivna naprezanja i tako dolazi do povećanja posmične čvrstoće. U ovom radu prikazana je metoda sniženja razine podzemne vode bunarima za pravokutne i nepravilne iskope. Proračun potrebnih bunara za sniženje razine podzemne vode napravljen je u programu GGU Drawdown. Pomoću programa GGU Drawdown također su napravljene parametarske analize utjecaja koeficijenta propusnosti, promjera i dubine bunara na konačan broj potrebnih bunara za željeno sniženje podzemne vode.

Abstract (english)

Groundwater control is used for various purposes, to prevent hydraulic failure, excessive uplift, inability to perform work in dry or negative impact to buildings. By lowering the groundwater, pore pressures and reduced which increase the effective stress and thus result in increased soil strength. This paper presents a water control by well dewatering systems , both for rectangular and irregular excavations. The calculation of the required wells for groundwater level drawdown was made in GGU Drawdown software. The parametric analyzes of the effect of the coefficient of permeability, diameter and depth of wells on the final number of wells required for a certain groundwater level drawdown is also performed.
