DAMAGE TO RAILWAY EMBANKMENTS IN THE 1968-TOKACHIOKI EARTHQUAKE

Railway embankments between Shiriuchi and Noheji stations on the Tohoku line suffered severe damage in the 1968 - Tokachioki earthquake. The damage was classified into four categories; slope surface flowslide; slope failure; vertical cracking; and subsidence of embankment. The causes of each type of failure are examined with due consideration for mechanical properties of fill materials, distribution of rainfall preceding the earthquake, and the effect of ground shaking, especially the increase of pore-water pressure due to cyclic loading. Some ideas for earthquake resistant design of embankment are presented. (Author)
