Abstract
The conventional Multiple Linear Regression model( MLR)is widely used in dam safety monitoring,but there is chaotic phenomena in residual series in this model,and the residual analysis is not implemented,which will affect the prediction accuracy. In this paper,a new MLR model combined with Bernstein polynomial was put forward by using RLS adaptive prediction algorithm that is based on Bernstein polynomial theory,namely it separates different influential components by MLR model,then uses RLS adaptive prediction algorithm to deal with the residual time series. Moreover,the model was validated by the observa-tion data of horizontal displacement of dam crest of Siˊnanjiang Hydropower Station. The validation results show that this model has higher prediction accuracy and can well reflect the actual value fluctuation.关键词
