Abstract

The 2011 off the Pacific coast of Tohoku Earthquake occurred on March 11. When the earthquake occurred, there were a number of frozen subsurface zones in cold districts, such as Hokkaido. However, any experimentally-verified case of deformation and collapse modes of embankment was not available in respect to the seismic performance of a frozen embankment. This study examined the earthquake resistance of embankment in cold districts by providing shake to a model embankment on which the surface layer had been frozen after adding seepage water. Additionally, a similar experiment was conducted for a model embankment on which the surface had not been frozen.
