It is urgent need of an accurate calculation method to forecast phreatic surface. Based on analysis of affecting factors of phreatic surface in tailing dam, the regression method of Random Forest (RE) was used to predict the phreatic surface. According to the daily observation of phreatic surface, the RE model for predicting phreatic surface was obtained. The proposed model was applied to analyze the stability of tailings dam. A practical case in China is given to illustrate analysis method based on presented RE model for predicting phreatic surface.
