摘要：This paper simulates two shaking table tests performing for ground
   liquefaction with seismic input of 0. 15 g and 0. 5 g as well as the
   Wildlife site where liquefaction was triggered during the Superstition
   Hills Earthquake,1987 using a fully coupled dynamic effective stress
   analysis. A modified generalized plasticity model is used to simulate
   cyclic mobility and liquefaction behavior of saturated sands. The
   parameters of the generalized plasticity model are calibrated from
   laboratory tests and conventional field investigations. The numerical
   results show that the simulated ground acceleration and the history of
   pore water pressure ratio accord well with the measurements. In
   addition,the calculated acceleration response spectra for the ground
   response correspond well with those of the measurements. Thus,the used
   fully coupled dynamic effective stress method is very effective in
   analyzing seismic response of liquefied site.
