Abstract: The commonly used expressions of results of slope stability evaluation, namely, these criteria for evaluation of slope stability are systematically summarized and analyzed in this paper. These criteria are 1) factor of safety; 2)reliability or probability of failure; 3) values of displacement, stress, velocity of displacement and others for rock mass of slope; 4) conclusions of qualitative experience; 5) disturbence energy; 6) rate of acoustic emission, etc.. On this basis, the main characteristics of all these criteria are analyzed, the suitable conditions application for these criteria and others are also reviewed.
