THE EFFECT OF LIQUEFACTION ON THE DAMAGES OF FACTRIES IN THE GREAT EAST JAPAN EARTHQUAKE DISASTER

Abstract

 Many factories at the reclaimed land in Kanto area were damged in the Great East Japan Earthquake Disaster, 2011. Some of the damages might be related to the liquefaction occurrence at the reclaimed land. Thus, for the future planning of the liquefaction coutnermeasures, it is beneficial to evaluate the effect of the liquefaction occurrence on the damage. In this study, based on the published data, the relationships between the economical loss (damages) to the factories, and seismic intensity nearby the site and liquefaction occurrence at the site were investigated. As a result, the increase of the damages to a factory due to the occurrence of liquefaction is evaluated.
