Seismic Centrifuge Modelling of Earth Dams

Abstract

Three dynamic centrifuge models were tested to obtain data for safety evaluation of the Jen-Yi-Tan Dam in Taiwan subject to a strong earthquake. in these tests, recorded 1999 Chi-Chi earthquake ground motions were modified and used on the electro-hydraulic shaking table mounted on the 400 g-ton centrifuge at the University of Colorado at Boulder. All tests were conducted under centrifugal acceleration of 150 g, and the input acceleration was scaled accordingly in order to simulate the given earthquake. a rigid container and water as pore fluid were used in the tests. in both Models 2 and 3, no sign of soil liquefaction was observed in the tests although a noticeable amount of settlements were found from the earth dam cross-section profile after testing. © 2010 Taylor & Francis.
