| Abstract: | Based on the former achievements and the known basic dynamic property of fly-ash dam, earthquake response tests of VI and Vll degrees simulation earthquake waves and failure tests have been done on the models of fly-ash dams with different dam crest elevations of 170, 180, 230 m by the large-scale shaking table, The earthquake resistance tests have been done on the models of ash dams heightened by three mixtures of ash and corresponding evaluations are given, The conclusions are beneficial to the research of earthquake resistance of ash dam and the earthquake attenuation and disaster prevention. |
