Cyclic undrained behavior and liquefaction resistance of transparent sand manufactured by fused quartz

In this paper, a series of cyclic torsional shear tests (TST) were used to study the cyclic undrained behavior and liquefaction resistance of saturated transparent sand manufactured by fused quartz. It was found that the saturated transparent sand has the similar cyclic undrained behavior with saturated natural sands. The mobilized angle of shearing resistance of saturated transparent sand is around 42.6° within the range of saturated natural sands which have angular shape. The saturated transparent sand has a similar trend of shear stress ratio versus number of cycles, but the liquefaction resistance is a little of higher than saturated natural sands.
