It is urgent need of an accurate calculation method to forecast phreatic surface. To analyze factors affected tailings dam phreatic surface, comprehensive model of phreatic surface prediction based on GM(Grey model) and SVM(Support Vector Machine) was established. The established model was used to a practical tailing dam in China. It shows that the model not only have the advantages of "accumulative generation" of a Gray prediction method, which weakens the original sequence of random disturbance factors, and increases the regularity of data, but also have full advantage of the SVM approximation performance with a fast solving speed,.
