ABSTRACT
Behavior of sand after liquefaction is discussed and formuled. Material properties that are usually assumed constant, such as internal friction angle, is ahown to change due to cyclic loading causing liquefaction. It is also shown that regions with very small stiffness appears by the cyclic loading. They may expand several ten percents, which causes liquefaction-induced large permanent displacement. A simlified model is introduced and improved so as to be able to take into new features such as change of material property and appearance of low stiffness region. The agreement of the numerical calculation and test are very good. Future research needs for evaluating the amount of liquefaction-induced permanent displacement more precisely are also pointed out.(AU)
