Abstract
This study is reasonable liquefaction prediction of Urayasu in case of the Great East Japan Earthquake based on RSPM. In the one-dimensional seismic response analysis use RSPM, the actual measurement and analysis value of maximum surface acceleration were congruous on the natural deposition ground. However, it was confirmed at the reclaimed land that maximum acceleration become small. In order to carry out reasonable liquefaction prediction in case of a trench type great earthquake, it was confirmed that it is necessary to take into consideration the regionality of a liquefaction strength ratio and the influence of a long-time continuation earthquake motion.
