Abstract
Heterogeni nekoherentni zrnati materijali sa značajnim udjelom šljunka imaju široku upotrebu pri izgradnji različitih nasipa, poboljšanju svojstava temeljnog tla i temeljenja. Poznavanje ponašanja takvih materijala, uključujući njihovu čvrstoću i deformabilnost, potreban je za praktičnu upotrebu. Za potrebe ovog rada provedeno je ukupno 15 pokusa u urežđaju za direktno smicanje s smičnim okvirom dimenzija 30 x 30cm, kako bi se istražilo ponašanje krupnozrnatog materijala: mješavina šljunka i pijeska. Ovaj rad fokusira se na posmičnom ponašanju materijala, utvrđživanju dilatativnog ponašanja: da li postoji i pokušati ga kvantificirati. Provedeno je pet serija ispitivanja na različitim kombinacijama mješavina odnosa šljunka i pijeska, a svaka serija pokusa provedena je pri tri različita vertikalna naprezanja. Kao rezultati pokusa prikazani su minimalni, maksimalni i kritični koeficijenti pora, normalizirane krivulje naprezanja, promjene visine uzorka tokom pokusa, normalne konsolidacijske linije i linije kritičnih stanja, vršni i kritični kut trenja te kut dilatancije. Uređžaj za izravno smicanje korišten u pokusima je jedan od rijetkih urežđaja u Hrvatskoj i šire. Njegova dobava omogućena je pomoću EU fonda iz Projekta „Razvoj istraživačke infrastrukture na Kampusu Sveučilišta u Rijeci”. Kao sastavni dio rada priložen je Dodatak A u kojem je opisan postupak provožđenja pokusa, a njegova namjera je da služi kao priručnik za korištenje uređžaja.
Abstract (english)
Heterogenous, non-cohesive materials, with significant amount of gravel are quite commonly used in construction of embankments, for improvement of foundation soil properties and foundation works. Understanding the behaviour of such materials, including their strength and deformation characteristics, is necessary for practical applications. For the purpose of this work a total of 15 direct shear tests on a large direct shear-box apparatus have been conducted, to investigate behaviour of coarse-grained materials: mixtures of gravel and sand. The focus of this work is on shear behaviour of material, its dilatancy: does it exist and try to quantify it. Five series of tests were conducted on different sand-gravel mixtures. Every series was conducted with three different vertical stress levels. Minimal, maximal and critical void ratio, normalized stress curves, changes in specimen height, normal consolidation lines and critical state lines, peak and critical friction angles and dilatancy angle are shown as test results. Direct shear apparatus used in tests is one of rarest in Croatia and wider. The financial help of EU fond from Project „Razvoj istraživačke infrastrukture na Kampusu Sveučilišta u Rijeci” enabled the acquisition of the apparatus. As a part of this work in Appendix A standard test procedure is described, and its purpose is to serve as apparatus test manual.
