TWO DIMENSIONAL SPATIAL SEVERITY OF LIQUEFACTION
|
抄録（英）：
Two dimensional spatial severity of liquefaction, when the spatial variations of relative density and permeability coefficient are interpreted as two dimensional stochastic fields, is estimated with the aid of the finite element analysis code DYNAFLOW(Ref.1). From the analysis, the spatial extent of liquefaction is found to be dependent upon the scale of correlation of the sample stochastic fields. Moreover, the quasi two-dimensional analysis involving a large number of (one dimensional) soil columns is found to result in a conservative estimation of liquefaction severity due to the lack of the two dimensional effect which tends to permit the dissipation of excess pore water pressure.
