| Abstract: | In this paper, the first five natural frequancies of the gravity dam are identified from the data obtained by means of dynamic model tests. A few isolation methods of closely spaced modes are presented as well. Finally, the isolation vibration modes are treated with optimal weighted orthogonalization. |
