| Abstract: | The theory and technology of shaking table model tests on earth-rockfill dams are systematically described and discussed. A model similarity design method based on static and dynamic characteristics tests of a prototypical model dam, and a vibration test method using input from ground motions of different intensities are proposed. Based on the performance parameters of a 1g large-scale shaking table and ng super-gravity centrifuge-shaking table equipment, advantages and disadvantages of shaking table model tests of earth-rockfill dams were analyzed. Combined with existing projects, the application of shaking table tests in earth-rock dam engineering was summarized. The evolution law of structural dynamic characteristics of a high concrete-faced rockfill dam under many strong earthquakes was studied. |
