Abstract: The stability of slope is influenced by multiple factors. It is one important subject to evaluate and predict the stability reasonably in the research of slope. Based on the approved grey correlation analysis and analytic hierarchy process (AHP), the comprehensive method is proposed to analyze the slope stability. According to the principle of grey correlation analysis, associate degree of slope stability is estimated and the slope grade is appraised by maximum correlation law. This method avoids the disadvantage that interval of the grade standards is not taken into account in traditional grey correlation analysis. The AHP of scale 3 is used to discuss the index weights; and precision of grey correlation analysis is improved. Case study shows that this method is reasonable and feasible to estimate slope stability.

Key words: slope, stability evaluation, grey correlation analysis, analytic hierarchy process
