摘要
研究了用小波分析提取效应量中趋势分量的方法,并探讨了趋势分量Logistic增长模型的建立方法。采用某碾压混凝土重力坝某测点的水平位移监测数据,建立了相应的Logistic增长模型,确定了模型参数,获得的位移趋势分量的最终稳定值可作为大坝安全监控的控制量。
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.
