New method for establishing mathematical model of dam safety monitoring

On the basis of regression model,the genetic algorithm is applied to improve the establishment of mathemiatical model for dam safety monitoring.It helps to overcome the under fitting problem usually occurred in regression.The application of this method to a slotted gravity dam located in the northeast of China is given as an example for demonstration.Hybrid model and genetic regression model for displacement of the top of the dam are established respectivelty.The calculation shows that by using this new method the fitting is greatly promoted.
