Cyclic stress conditions causing liquefaction of sand
Quantitative data were obtained necessary to produce liquefaction; under cyclic loading, different conditions must be considered; initial liquefaction, partial liquefaction, complete liquefaction, and failure; at relative densities below about 50%, these conditions occurred almost simultaneously, whereas for relative densities above about 80%, considerable number of stress cycles were required after initial liquefaction to develop large strains defining failure condition; there was approximately linear relationship between relative density and stress required to cause initial liquefaction in given number of cycles, and between initial liquefaction increase and confining pressure, to predict susceptibility of field deposit to liquefaction during earthquake.
