| Abstract: | This research was to reveal the variation regularity of observed dam behavior in the frequency domain,and to make quantitative analysis on the causes of variation.With a gravity dam as a case study,we analyzed the spectrum of monitoring data sequence of dam behavior in service,and established a model to analyze the coherence relation between effect quantity and influence quantity from the aspect of system identification.Through comparison between the results of time-domain analysis and frequency domain analysis of prototype monitoring data sequence,we confirmed the feasibility and validity of this approach. |
| Keywords: | dam monitoring data spectrum analysis coherence analysis |
