Abstract (english)
This paper presents a laboratory and numerical study to determine three hydraulic characteristic curves of a swelling material (soil or rock) in which montmorillonite is the predominant type of mineral. The first, the soil-water characteristic curve, represents the relationship between suction and moisture content that needs to be defined to solve the water flow problem and the accompanying change in the volume of the swelling unsaturated porous medium. The second curve presents hydraulic conductivity as a function of saturation or suction. The third curve represents the relationship between the volume change and the moisture content of the swelling material. These curves are crucial for understanding water flow and volume changes in swelling materials, with this study focusing on wetting regime behaviour. The aim of this research was to establish reliable methods for the definition of the hydraulic properties of the swelling material and to verify a proposed swelling model. While the swelling material shows significant hysteresis between the drying and wetting regimes, the hydraulic conductivity function shows little or no hysteresis between drying and wetting paths at equal moisture contents (coefficients).
Abstract (croatian)
U radu je prikazana laboratorijska i numerička studija za određivanje triju hidrauličkih karakterističnih krivulja bubrivoga materijala (tla ili stijene) u kojemu je montmorilonit prevladavajući tip minerala. Prva, karakteristična krivulja tlo-voda predstavlja odnos između usisa i vlažnosti koji je potrebno definirati za rješavanje problema tečenja vode i prateće promjene volumena bubrivoga nezasićenog poroznog medija. Druga je krivulja funkcija hidrauličke provodljivosti u ovisnosti o saturaciji ili usisu. Treća krivulja predstavlja odnos između promjene volumena i vlažnosti bubrivoga materijala. Poznavanje ovih krivulja presudno je za razumijevanje tečenja vode i rezultirajućih promjena volumena pri čemu se studija posebno usredotočuje na ponašanje bubrivoga materijala u režimu vlaženja. Cilj istraživanja bio je utvrditi pouzdane metode za određivanje hidrauličkih svojstava bubrivoga materijala i obaviti verifikaciju predloženoga modela bubrenja. Iako bubrivi materijal pokazuje znatnu histerezu između režima sušenja i vlaženja, funkcija hidrauličke provodljivosti pokazala je malu ili nikakvu histerezu među putevima sušenja i vlaženja pri jednakim sadržajima (koeficijentima) vlažnosti.
