Abstract: In this paper, the artificial neural network (ANN) and support vector machine (SVM) methods which are commonly used in data mining are introduced, both the advantages and disadvantages of between them are detailedly discussed in engineering application. Two forecasting models based on ANN and SVM are derived from the main factors for slope stability, in which the nonlinear relations between slope stability and main influencing factors are obtained from the finite empirical data. Compared the results with maximum likelihood estimation in details, it is concluded that SVM forecasting model has more advantages to slope stability evaluation over ANN model under the condition of limited data.
