Abstract

Previous research shows that shaking history affects the liquefaction resistance of the soil. A strong shaking event could reduce the soil liquefaction resistance due to increased anisotropy of soil. However, a mild shaking with partial or no liquefaction could greatly increase the liquefaction resistance. In this paper, the effect of shaking history on liquefaction resistance of sand is studied using 1-g shake table testing. A uniform liquefiable sand deposit was air-pluviated and fully saturated in a large laminar shear box (L×W×H: 2.29 m×2.13 m×1.83 m). The sand deposit was subjected to four different shaking events. Piezometers were embedded at different depths to capture the seismic response of sand deposit. The excess pore pressure readings from four shaking events were compared to investigate the effect of shaking history on liquefaction resistance of the sand deposit. The major findings of this paper are: (1) along with the shaking, the sand deposit became denser; (2) the shaking event with an amplitude of 0.25 g tended to densify the sand and increase the liquefaction resistance; and (3) the strong shaking with an amplitude of 0.4 g tended to damage the soil structure and reduce the liquefaction resistance.
