Liang Hui Li, Sheng Jun Peng, Zhen Xiang Jiang, Bo Wen Wei · Applied Mechanics and Materials · 2014
By using unscented kalman filter (UKF) theory and introducing adaptive factor into BP neural network, a new prediction model of concrete dam deformation was proposed. Example shows that this model can improve the convergence speed of BP neural network, and the calculation precision of this model meets engineering requirements. Meanwhile, this model can be applied in the safety monitoring of other hydraulic engineering structure.
