According to the characteristics of the inevitable fuzziness and andomness in the slope stability evaluation,we proposed the model of rock slope stability evaluation based on cloud model, combined the combination weighting game theory considering subjective and objective weight,evaluate the slope instances.The comprehensive cloud of each factor on each stability level has been generated based on 7 indexes and evaluation standard.According the actual slope data,the degree of certainty for each slope on each stability level can be obtained.Finally,the maximum degree of certainty determined the slope stability level.Comparing the cloud model method with the grey correlation analysis and extension evaluation,proved that this evaluation result is reliable, the method is feasible and effective.
