タイトル(英): SIMPLIFIED EVALUATION OF GROUND DEFORMATION DUE TO LIQUEFACTION FLOW
抄録(英): In evaluating the ground deformation due to liquefaction-induced flow, it is important to evaluate adequately not only rigidities of liquefied layers, but also those of non-liquefied layers above water level. In this paper, taking notice of shear modulus of non-liquefied layer, simplified FEM analyses were conducted. Influences of rigidity of non-liquefied layer and nonlinearity of rigidity on ground deformation are discussed. It indicated that the case considering nonlinearity of non-liquefied layers express damages more properly than the case rigidity of non-liquefied layers are constant, and, the case shear modulus change in accordance with distance from quay wall also agreed well with investigation.
