In order to solve the safety evaluation of the stability of the tailings dam under earthquake,an evaluation model combining gray relational analysis and variable weight theory is proposed.Taking a uranium tailings pond in the south as an example,tailings dam slope,shear strength,porosity and water quantity of ten dams are measured.Finally,the gray relational degree and variable weight theory are used to calculate and sort the correlation index of each dam body.The results show that the stability of the first dam(1~# dam) is the best,and the stability of the initial dam(6~# dam) and the combat ...
