飽和砂の液状化現象に関する考察(2報)

Abstract

The phenomenon of liquefaction of saturated sand at the time of earthquake was analyzed byassuming simplified stress conditions. The results of this analysis were applied to the study ofcyclic triaxial shear test under fixed values of mean principal stress. The actual earthquakes, however, confer irregular vibrations upon the ground, and the principle of analysis which is based onsuch simplified stress condition can not be applied, in its unmodified form, to practical designs. Inthis respect, some tests were carried Out to investigate the influence of irregular vibrations on theliquefaction of saturated sand.
