摘要：

The dynamic property tests were done on the models of fly-ash dams at the elevations of 170m, 180m and 230m of a power station by the large-scale shaking table with two conditions of submerged and non-submerged beaches. The earthquake-resistance properties of the models of 180m-ash dams heightened by three mixtures of fly ash are analyzed and the conclusion is drawn that three mixtures have little influence on the dynamic property of dam. The tests also show that the natural frequency of dam and the acceleration amplification factor at the top of dam decrease with the increases of excitation acceleration and the height of dam; and both are lower under the condition of submerged beach.
