Analysis of Trend Component in Dam Safety Monitoring
Qilong Bi · Water Resources and Power · 2011
Wavelet analysis is applied to extract trend component from effect variable.And the establishment process of trend component Logistic model is discussed.Then a trend component Logistic model is established by using the horizontal displacement monitoring data of RCC gravity dam observation point.Finally,the model parameters are determined and the final stable value of trend component of the displacement is obtained,which can be used as a control threshold of dam safety monitoring.
