An extension cluster space predication method for stability of rock-mass slope

Based on the matter element model and the cluster analysis method, an extension cluster space prediction method for the stability of rock-mass slopes is proposed in this paper. In the method, the stable types and the influence factors of rock-mass slopes are used to set up the classical matter elements and limited matter elements. A simple forecasting model of the stable types of rock-mass slopes is founded by applying the related functions of matter elements and extension sets. The predicting results of the stability of rock-mass slopes are obtained by applying the extension cluster analysis. The analyzing result of an example shows that this method is satisfied.
