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。

Aiming at the complex huge system of dam,nonlinear combined model of the dam based on wavelet network is introduced for taking advantage of useful information on the observation values.The nonlinear combined prediction model of dam based on wavelet network is established by using wavelet theory and artificial neural network.Taking the fitting and prediction of Longtan concrete dam for an example,the calculation results are in accord with the measured values.Thus,it shows that the proposed method is feasible and effective.
