A methodology that provides a ground motion time history at paleoliquefaction sites is presented. The methodology presented uses the Meramec site as an example paleoliquefaction feature, and modeling the dynamic soil behavior during liquefaction using an effective stress approach. This paper presents a research effort using a one dimensional non-linear site response analysis, with assessment of pore water pressure build up, in addition to site characterization of the liquefaction features. Thus site-specific conditions and the non-linear response of soils are both taken into account.
