Abstract:This paper presents measurements, and an interpretation of these measurements, based on the use of bender-element probes for Boštanj silty sand. The samples were prepared at different initial void ratios and isotropically compressed up to 5 MPa. The bender-element technique was used to determine the dynamic shear modulus (G0) of the soils at very small strains. The multiple bender-element probes were shot at different excitation frequencies in order to increase the reliability of the measurements. The G0 stiffness was determined by using three different techniques: a) the first-time arrival, b) the phase-change method and c) the cross-correlation method. The systematic differences observed between the G0 values, calculated using the three techniques, are discussed. The variation of G0 in the logG0 - logp′ plane was evaluated for the Boštanj silty sand and compared with other sands.

Title:Merjenje in interpretacija togosti meljastega peska iz Boštanja pri zelo majhnih deformacijah
Abstract:V članku je predstavljeno merjenje in interpretacija meritev z bender elementi na meljastem pesku iz Boštanja. Vzorci so bili pripravljeni pri različnih začetnih količnikih por in obremenjeni v izotropni kompresiji do 5MPa. Tehniko merjenja z bender elementi smo uporabili za določitev dinamičnega strižnega modula (G0) materiala pri zelo majhnih deformacijah. Zanesljivost meritev smo povečali z uporabo skupine signalov z različnimi frekvencami vzbujanja. Togost G0 je bila določena z uporabo treh različnih pristopov, in sicer: a) časovnega prihoda vala, b) spremembe faze in c) navzkrižne korelacije. V članku so pojasnjene razlike med vrednostmi G0 glede na uporabo določenega pristopa, ki so se sistematično pojavljale. Prikazano je spreminjanje togosti G0 meljastega peska iz Boštanja v ravnini logG0 - logp′ in primerjave z drugimi peski.
Keywords:meljast pesek, triosne preiskave, togost pri zelo majhnih deformacijah, bender elementi, meritve v časovni in frekvenčni domeni
