“…Schematic explanation of silt-sand mixture is depicted in Fig. 3 (Yamamuro and Covert, 2001). As it can be understood there are about 3 transitional zones between two extremes in most of the cases in sand-silt mixtures.…”

“…According to Yamamuro (2001), when 40z silt content (high silt content) is contained in a sand specimen, no rapid switch from contractive to dilative behavior at low strains takes place and the behavior is highly contractive. This contractive behavior extends to much larger axial strains than that observed in sands including low silt content.…”

“…The fabric of loose specimens of silty sands obtained by AP also has been shown to be highly contractive (Lade and Yamamuro 1997;Yamamuro and Covert 2001;Zlatovic and Ishihara 1997). Lade and Yamamuro (1997) attributed the highly contractive behavior of AP silty sands to the unstable floating fabric obtained with their method of specimen preparation (Yamamuro and Wood 2004).…”

ABSTRACT:A new method of specimen reconstitution is presented that is appropriate for element testing of sands containing either plastic or nonplastic fines. The method allows reconstitution of homogeneous, saturated specimens of sands containing fines whose stress-strain response closely resembles the stress-strain response of natural soil deposits formed underwater (e.g., alluvial and offshore submarine deposits, hydraulic fills, and tailings dams). A procedure is described to evaluate the maximum void ratio (e max ) of sands containing fines under conditions that more appropriately represent soil deposition at its loosest state in aquatic environments. For soils deposited in water, the data obtained with the procedure proposed in this paper suggest that ASTM D 4254 overestimates the e max of sands containing plastic fines and underestimates the e max of sands containing nonplastic fines.

“…Liquefaction is mostly observed in sandy soils, but the results of comprehensive investigations carried out in the last decades have shown that sands containing some portion of a fine fraction may liquefy as well (Yamamuro andCovert 2001, Boulanger andIdriss 2006).…”

This paper presents and discusses the results of numerical modelling of pore water pressure build-up in post-flotation saturated tailings deposited at the Tailings Storage Facility "Żelazny Most", caused by seismic-induced dynamic loading. Numerical simulations were based on the compaction/liquefaction model proposed by A. Sawicki. The model parameters were determined in the laboratory for tailings sampled at the TSF "Żelazny Most". The sensitivity of the numerical model was verified in a series of numerical tests for various horizontal acceleration amplitudes. In the main calculations, an accelerogram recorded during a real paraseimic event was assumed. The results obtained show that, with the current seismic activity near the TSF "Żelazny Most", some pore water pressure is generated within the saturated tailings layer, but it does not trigger the liquefaction phenomenon.
