Abstract

Prikazani su rezultati numeričkog modeliranja procjeđivanja ispod brane s zagatom, koji se nalaze u stijeni međuzrnske poroznosti. U varijantnim rješenjima hipotetske prostorne domene promatra se utjecaj promjene duljine nožice gravitacione brane s zagatom na brzine i ukupne protoke procjeđivanja. Korišten je 2D model u vertikalnoj ravnini s horizontalnom razinom tla i nepropusnom podinom. Korišten je model konačnih diferencija. Rezultati su pokazali da produljenje duljine nožice s 20m na 40m i 60m uzrokuje smanjenje intenziteta procjeđivanja za 10,93 % i 21,26 %, uz konstantnu dubinu uranjanja zagata.

Abstract (english)

The results of numerical modeling of seepage flow under the dam are found for the rock of intergranular porosity. In variant solutions of the hypothetical spatial domain, the influence of the change in the length of the gravity dam with the impermeable vertical screen on the velocities and the total flow rates of seepage is observed. 2D models were used in the vertical plane with horizontal ground level and impermeable layer. A finite-difference model was used. The results showed that extending the length of the dam from 20m to 40m and 60m causes a decrease in the seepage intensity by 10.93% and 21.26%, respectively, with constant immersion depth of the impermeable vertical screen.
