The safety of red mud yard not only affects the production during operation,but also threatens the safety of downstream life and property.How-ever,there are few studies on the safety evaluation of red mud yard.In order to better address the above problem,this paper studies the impact of multi-factor changes on the safety of the red mud yard,and a safety evaluation model for the red mud yard is established.Firstly,based on the analytic hierar-chy process(AHP)and extension theory,the influence degree of each evaluation index on the red mud yard is analyzed.According to the different char-acteristics of red mud,the state values of 9 evaluation indexes are determined from three aspects:dam body safety,reservoir flood control safety and hu-man factor,and the multi-level evaluation principle is used to establish the safety evaluation hierarchy system.Then,each index is quantified,while its weight and grade comprehensive correlation degree are determined,so as to realize the safety grade evaluation of red mud yard.This method is used to e-valuate the safety grade of a red mud yard in Shanxi province,and the safety level is 3,which belongs to the general safety state.After comparing with the field test results,it proves that the model can effectively evaluate the safety of the red mud yard.
