Abstract (english)
Knowledge about soil permeability is important in various scientific fields: hydrology and hydrogeology, geotechnics, environmental geotechnics, and others. Depending on the different goals that need to be achieved by a particular engineering project, the conditions in which the permeability coefficient is determined in terms of applied hydraulic gradients, applied stresses, type of test fluid, etc. are adjusted, as well as the required precision of its determination. In addition, the permeability coefficient is a soil property with the largest range of possible values. It can be determined through various laboratory and field methods, and by applying established empirical correlations using data on the grain-size distribution and empirical coefficients that depend on some factors, such as hydraulic radius (specific surface), curvature, porosity, etc. This paper presents the results of laboratory testing of the permeability coefficient by the constant head test and the use of a permeameter. The results were compared with the permeability coefficient obtained by applying a number of empirical correlations. Artificial samples were prepared in the laboratory by mixing different previously prepared soil fractions in order to determine the influence of particle size and soil gradation on the estimated soil permeability coefficient.
Abstract (croatian)
Poznavanje koeficijenta propusnosti tla važno je u različitim znanstvenim područjima: hidrologiji i hidrogeologiji, geotehnici, geotehničkome inženjerstvu okoliša i drugim. S obzirom na različite ciljeve koje treba postići određenim inženjerskih zahvatom, prilagođavaju se uvjeti u kojima se laboratorijski određuje koeficijent propusnosti tla poput veličine hidrauličkoga gradijenta, primijenjenih naprezanja, vrste ispitnoga fluida i slično, a prilagođava se i potrebna preciznost njegove odredbe. Osim toga, koeficijent propusnosti svojstvo je tla koje ima najveći raspon mogućih vrijednosti. Moguće ga je odrediti različitim laboratorijskim i terenskim metodama te primjenom poznatih empirijskih korelacija uz korištenje podataka o granulometrijskome sastavu porozne sredine. U ovome radu prikazani su rezultati laboratorijskih ispitivanja koeficijenta propusnosti metodom sa stalnom razlikom potencijala i korištenjem permeametra te su uspoređeni s koeficijentom propusnosti dobivenim upotrebom većega broja empirijskih korelacija. Korišteni su uzorci pripremljeni u laboratoriju miješanjem različitih prethodno pripremljenih frakcija tla, kako bi se mogao utvrditi utjecaj graduiranosti tla i veličine čestica na koeficijent propusnosti tla. U radu je pokazano kako se ne može dobiti dovoljno pouzdan koeficijent propusnosti tla samo korištenjem empirijskih korelacija. Iako je područje primjene određene korelacijske veze bilo zadovoljeno, izračunani koeficijenti propusnosti u nekim slučajevima znatno su se razlikovali od onih izmjerenih u laboratoriju. Svaka od gore navedenih metoda ima svoje prednosti i nedostatke te je tek upotrebom dviju ili više metoda moguće dobiti projektni parameter tla koji je dovoljno pouzdan.
