✦ Synopsis

This paper describes the behavior of and damage to large ®ll dams during earthquakes. Although ®ll dams have been constructed since olden times, there are only records of recent earthquake damage. We analyzed the behavior of ®ll dams of at least 15 m in height during earthquakes, and investigated the damage to the ®ll dams. The fact that ®ll dams that are designed and constructed based on the modern design standards have never been failed but have been only slightly affected by past earthquakes in Japan and other nations suggests that such large ®ll dams are highly earthquake resistant. The modern conventional design methods (soil engineering control of the bank soil, method for evaluating slip safety, and evaluation method of the foundation ground) are thus fully adequate for determining earthquake resistance.
