This study analyzed the correlations between earthquake vibrations and their associated damage based on the data of past earthquake damage in the Hokkaido and Kagoshima areas.The vibration-damage correlation was examined by statistic analysis of the effects of earthquakes based on the characteristics of the ground,and suggestions concerning the forecast of damage were made as a measure for reducingearthquake damage.Statistic analysis of the vibration-damage correlation was conducted using the equationof accelerated velocity-distance damping caused by estimated earthquake vibrations and geologicaldata of the damaged area meshes of embankments,slopes and structures.By focusing on the ground classification for each earthquake,the damage rates(correlation)were compared using the acceleration estimated from the earthquake vibrations at the damage areas. |
