In order to investigate the influence of internal and external factors on the safety state of the tailings dam，a method for analysing the safety state of the tailings dam based on heterogeneous hierarchical diagrams was proposed. Firstly，a hierarchical causal graph was constructed based on a priori knowledge to link key factors such as environment，seepage field and stress field with the safety status of tailing dams，and an evaluation index system was established by combining the attribute characteristics of heterogeneous nodes. Secondly，the cloud model and set-pair analysis theory were used to quantitatively calculate the potential logical relationship between the heterogeneous causal graph and the safety stability of the tailings dam. A dynamic interval calculation method for quantitative indicators and a safety status level calculation model were proposed to convert the fuzziness and uncertainty of complex and diverse evaluation indicators into quantitative expressions. Finally，a tailings dam in Luoyang was used as an example to verify the scientificity of the model.The results show that the model can quantitatively analyse the link between factors and states and identify the causes of negative changes in stacked dams. The conclusions of the model analysis can be used for the safety management of the dam-building process.
