ダム耐震に関するレポート Martin Wieland氏（ICOLD、ダム耐震技術委員会委員長）
Attached please find a paper on the need for the seismic safety evaluation of dams, which was published in Water Power and Dam Construction in February 2023, when the two catastrophic earthquakes occurred in the Southeast of Turkey. Although, according to the available information, most of the large dams performed well, there are a few cases where older embankment dams were damaged but did not fail. This is the right time to remind you that both new and old dams must satisfy the same safety criteria. For the verification of this requirement a seismic safety reevaluation is necessary. This has been a long-time recommendation of the ICOLD Committee on Seismic Aspects of Dam Design. You may help to initiate such safety evaluation programs in your country or organisation, if it has not yet been done. Further details are given in the attached paper.
With my best regards
Dr. M. Wieland
Chairman, ICOLD Committee on Seismic Aspects of Dam Design
