针对大坝这一复杂的巨系统,为尽可能利用观测量的有用信息,引入了大坝非线性组合分析模型,并基于小波理论及人工神经网络原理构建了小波网络的大坝非线性组合预测模型。以龙潭混凝土大坝为例进行拟合和预测,计算结果与实测值吻合良好,表明本文方法可行、有效。 In order to make use of the useful information of observation data, aiming at the complicated huge system of dam, this paper introduces dam non-linear combination analysis model, and based on wavelet theory and artificial neural network principle, constructs the dam nonlinear combination forecast of wavelet network model. Taking Longtan concrete dam as an example, the fitting and prediction are carried out. The calculated results are in good agreement with the measured values, which shows that the proposed method is feasible and effective.
