Improving Dam Seepage Prediction Using Back-Propagation Neural Network and Genetic Algorithm

الملخص EN

Statistical model is a traditional safety diagnostic model for dam seepage.

It can hardly display the nonlinear relationship between dam seepage and the load sets and has the disadvantage of poor extension prediction.

In this paper, the theories of Back Propagation Neural Network (BPNN) combined with Genetic Algorithm (GA) are applied to the seepage prediction model.

Taking a typical dam in China as an example, the prediction results of BPNN-GA model and statistical model are compared with the monitoring values.

The results show that the improved dam seepage model enhances the ability of nonlinear mapping and generalization and makes the seepage prediction more accurate and reasonable in the near future.

According to the established criterion, the safety state of the dam in flood season is evaluated.
