ABSTRACT
The behavior of water-saturated granular materials subjected to undrained deformations has been thoroughly investigated by several authors in past years. Typical examples of this type of work are the papers by Castro (1969), Casagrande (1976) and later by Vaid and Chern (1983). Most of the published work which concerns us here is based on the static or cyclic behavior of sands tested in the triaxial (cylindrical) apparatus. Some papers deal with tests in the torsional (Tatsuoka et al., 1982) or the simple shear apparatus (Alarcon-Guzman et al., 1988). Professor Ishihara (1993) in his Rankine Lecture on ‘Liquefaction and Flow Failure during Earthquakes’ gives a thorough and exaustive reference to published works in the subject.
