Abstract

There has been increasingly high intensity of acceleration ever recorded during earthquakes in recent times. In consistence with this trend several characteristics have been unearthed regarding performances of rockfill dams. With due considerations to these, damage features of high rockfill dams during recent earthqukes in Japan and China are briefly introduced herein, together with those previously reported. As an indicator of overall distress to the dams, the crest settlement was taken up and it was shown that the settlement tends to increase up to about 1.5% of the height of the dam with increasing acceleration during earthquakes.

Performances of Rockfill Dams During Recent Large Earthquakes

San Diego, California

There has been increasingly high intensity of acceleration ever recorded during earthquakes in recent times. In consistence with this trend several characteristics have been unearthed regarding performances of rockfill dams. With due considerations to these, damage features of high rockfill dams during recent earthqukes in Japan and China are briefly introduced herein, together with those previously reported. As an indicator of overall distress to the dams, the crest settlement was taken up and it was shown that the settlement tends to increase up to about 1.5% of the height of the dam with increasing acceleration during earthquakes.
