ABSTRACT
A theory of dynamic analysis was derived in order to make it possible to follow the time history of lateral ground motion triggered by seismic liquefaction. This theory obtains a single-degree-of-freedom differential equation, by solving which the time history is calculated. Since the equation have a viscous term and a residual strenght that need a detailed study to understand, model shaking tests were perfomed. Those tests revealed that liquefied sand has a rate-dependent nature that is viscous as well as that the magnitude of the residual strength of liquefied sand is strongly affected by the presence of inertia force. Consequently, several cases were analyzed and compared with observation. Their agreement seems to be good.(AU)
