Aiming at the deficiency of traditional dam deformation monitoring

a stepwise regression model with artificial bee colony algorithm（ABCA）is proposed for dam deformation monitoring in this paper.Firstly

the predictor variables are selected by stepwise regression

and the main statistical methods used include:correlation analysis

multiple co-linear relation and so on.Then the coefficients of the regression model are reevaluated by an improved artificial bee colony algorithm.ABCA is a novel swarm intelligence optimization algorithm

and it is introduced into dam health monitoring in this paper.Meanwhile

to improve the performance of local search of ABCA

the simplex operators are introduced into the basic ABCA.Examples show that the proposed model for dam deformation monitoring is more effective compared to similar models

considering it can simply the prediction model and improve the accuracy of fitting and prediction.
