摘要

In recent years, catastrophic earthquakes have become more frequent, as have instances of damage to water-power installations, so the International Commission on Large Dams ICOLD has urgently devoted much attention to geodynamic effects on dams and related structures in order to provide for resistance to strong earth movements. The topics have been surveyed regularly at ICOLD congresses and at annual meetings of the Committee on Seismic Aspects of Designing Dams, while the important topic has also been considered at special international forums in Tokyo (1995), Luxembourg (1997), Barcelona (1998), and New Zealand (2000). International collaboration in the ICOLD framework led to the issue of four bulletins on these topics in 1998-9: "Neotectonics and dams," "Guidelines on seismic observations on dams," "Guidelines on designing seismically resistant dams and auxiliary structures," and "Guidelines on designing dam features to resist seismic movements of the ground effectively." In this brief survey, I present only the major ICOLD approaches to geodynamic effects on large dams.
