The earthquake induced liquefaction of dam foundation was analyzed using an effective-stress based, fully coupled dynamic analysis method, in which the behavior of the sandy soil is described by means of a cyclic mobility constitutive model. The paper is primarily concerned with different responses under design water table and dead water table in a reservoir. The results show that the cyclic mobility constitute model can reflect the dynamic response of liquefiable soils, and that the liquefaction zone under dead water table decreases compared with the case of design water table, but the liquefaction induced deformations increase obviously in the upstream.

Key words: dam foundation, liquefaction, cyclic mobility, effective stress method, dynamic analysis
