FACTORS AFFECTING LIQUEFACTION AND CYCLIC MOBILITY-CLOSURE

In this closure to the discussion, the authors comment on the points made by the discussers, namely, (1) the writers use of sigma sub 3c as the independent variable rather than sigma sub 1c, (2) cyclic mobility nomenclature, with specific reference to the use of the terms cyclic mobility and liquefaction, and (3) the effect of nonuniform volume changes on the results of cyclic triaxial tests as compared with monotonically loaded triaxial tests. It is noted that even when comparing tests at the same sigma sub 1c, the cyclic triaxial tests on clean sand indicate that the sand would deform less during earthquakes if the initial shear stress is high (as under shear slopes) than if the shear stress is low. The authors attempt to clarify their use of the terms cyclic mobility and liquefaction and also explain their greater concern with nonuniformities in cyclic load tests than in monotonically loaded tests.
