英文摘要
A series of undrained hollow cylindrical cyclic torsional shear tests with initial shear were conducted on saturated Toyoura sand to reveal the effects of initial shear on large deformation properties of liquefied sand. By extending a numerical model that had been developed to simulate the liquefaction behavior without initial shear, the test results with initial shear could be reasonably simulated. In addition, a stacked-ring simple shear test apparatus was newly constructed, and it was employed to reveal the effects of liquefaction history on re-liquefation properties.
