FACTOR AFFECTING LIQUEFACTION AND CYCLIC MOBILITY

Alternative interpretations of test data which leads to conclusion different from those given by the authors are presented. Examination and replotting of cyclic test data indicates that the undrained shear resistance is determined mainly by the major principal consolidation stress and only slightly, if at all, by the consolidation stress ratio. Also, use of sigma sub 1C (which influences void ratio) rather than sigma sub 3C yield more consistent results (e.g. soil deformation during earthquake increases with initial shear stress rather than decreases) than those of the authors. It is noted that nonuniform volume changes are found in monotonically loaded undrained tests and are not uniquely to cyclic loading, as assumed by the authors.
