Abstract
Na slabo graduiranom pijesku, uzorkovanog u rijeci Dravi, provedena su troosna ispitivanja cikličkog ponašanja u nedreniranim uvjetima. Svi pokusi provedeni su uz kontrolu vertikalne deformacije. Ispitani su utjecaji frekvencije 0.1 Hz i 0.05 Hz, relativne zbijenosti od 33%, 50% i 80% te efektivnog naprezanja od 100 kPa, 200 kPa i 400 kPa. Rezultati pokusa su potvrdili pretpostavku da je likvefakcija pijeska popraćena porastom pornih pritisaka koji su nastali uslijed velikih deformacija. Degradacija pijeska se očituje i smanjenjem nosivosti tla, padom vrijednosti sekantnog posmičnog modula, rastom prigušenja kroz cikluse smicanja te rastom parametra prigušenja. Također, pri malim deformacijama zabilježeno je ojačanje materijala prije degradacije.
Abstract (english)
Undrained cyclic triaxial shear tests were conducted on poorly graded sand sampled from Drava river. All tests were performed using strain-control test method. Effects of two different loading frequencies (0.1 Hz and 0.05 Hz) were studies, as well as different relative densities (33%, 50% and 80%) and effective confining stresses (100 kPa, 200 kPa and 400 kPa). Obtained results confirmed the premise that liquefaction of sand is accompanied with the rise of the pore water pressure which is caused by large cyclic shear strains. Degradation of sand is manifested through reduction in bearing capacity, decreased values of the secant shear modulus, increased damping coefficient and increased damping parameter. Also, at lower amplitude shear strains material hardening was noticed prior to degradation.
