Abstract : Due to ongoing research efforts scientific information about earthquake effects on earth dams is increasing. Numerical and physical modeling techniques are being updated to improve the understanding of how an earth dam reacts to seismic events. Improved analysis methods for evaluating liquefaction potential and loss of soil strength due to earthquake motions, loss of dam freeboard due to soil deformations, and case histories of dam performance in earthquakes are emerging. For existing earth dams, the engineering challenge is to apply the emerging scientific database to each dam for the purpose of determining if the dam is adequately designed and built to safely withstand anticipated seismic events. In addition selecting the most beneficial and economical engineered remediation option for rehabilitating an existing dam remains a challenge. Engineers and scientists at the U.S. Army Engineer Waterways Experiment Station (WES) Geotechnical Laboratory are expanding the knowledge database for seismic research in soil properties, numerical analysis technique refinements and dam remediation analyses.
