Abstract
There is a worldwide interest in the proper seismic design of embankment dams in high seismic hazard zones. The seismic behavior of embankment dams can be evaluated by in-situ dynamic tests (such as processing recorded earthquake signals on dam body), experimental methods (i.e. experiments using large shaking table, centrifuge tests) and numerical methods Using recorded earthquake signals on dam body is a powerful tool for researchers for dynamic analysis of embankment dams. In this research, recorded accelerograms are used to dynamic analysis of Masjed Soleiman embankment dam, the highest rockfill dam in Iran. Using recorded earthquake signals in the basement of the dam as input excitation, dynamic analysis of the dam body was also performed and the results of the numerical modeling was compared with recorded earthquake signals on the dam body. The calculated responses are compared with recorded accelerograms on mid-height and crest of the dam. In comparison, the modern signal processing method, Time-Frequency Distribution (TFD), is used. This comparison leads to more appropriate modeling of the dam body in earthquake loading condition. The results indicate that TFD results show that %20 to 30% mass foundations have closer results to the recorded earthquake signal.
