Investigation on Stiffness Recovery of Liquefied Sandy Ground after Liquefaction Using Shaking-Table Tests

Ye, B. / Yokawa, H. / Kondo, T. / Yashima, A. / Zhang, F. / Yamada, N.

In this paper, shaking-table tests on saturated sandy model ground were carried out. During strong motions, responses in different position inside model ground, including acceleration and pore-pressure, were measured and investigated in detail. As soon as the motion stopped, hammer strikes were applied to the bottom plate of shaking-table with some time space interval. Through calculating the time difference when shear-wave pass through different accelerators, time history of shear-wave velocity was acquired and the process of stiffness recovery was analyzed.
