Safety Monitoring Model of a Super-High Concrete Dam by Using RBF Neural Network Coupled with Kernel Principal Component Analysis

Abstract: Effective deformation monitoring is vital for the structural safety of super-high concrete dams. The radial displacement of the dam body is an important index of dam deformation, which is mainly influenced by reservoir water level, temperature effect, and time effect. In general, the safety monitoring models of dams are built on the basis of statistical models. The temperature effect of dam safety monitoring models is interpreted using approximate functions or the temperature values of a few points of measurem… Show more

“…Unfortunately, the time‐dependent deformation is unable to be measured directly and can only be extracted from the measured data. Although sometimes this deformation can be negligible for operation periods, 11 it is an important predictor for initial impoundment periods 15–17 . All published mathematical expressions of the time‐dependent deformation are monotonically increasing functions with time 3,6,11,12 .…”

“…Although sometimes this deformation can be negligible for operation periods, 11 it is an important predictor for initial impoundment periods. [15][16][17] All published mathematical expressions of the time-dependent deformation are monotonically increasing functions with time. 3,6,11,12 However, in accordance with the detailed studies, this deformation does not always conform to the assumption of the monotonically increasing functions.…”

“…Generally, the prediction models are mainly divided into point prediction and interval prediction according to different prediction forms. These point prediction methods have been applied in the field of temperature prediction, including back-propagation neural network [19,20], artificial neural network [21], gray model [22], genetic algorithm [23,24], and support vector machine [25,26]. However, point prediction only provides one prediction result at each target point, which lacks uncertainty estimation [27,28].…”
