摘要
为了解决在极端条件(地震)下尾矿库坝体稳定性的安全评价问题,提出灰色关联度与变权理论相结合的评价模型。以南方某铀尾矿库为例,将10个坝体依据尾矿堆坝坡、抗剪切强度、孔隙度、含水量四个方面进行指标取值;最后,利用灰色关联度与变权理论计算出各坝体稳定性关联度指标并进行排序,结果表明:在南方某铀尾矿库的10个坝中,第一拦水坝(1~#坝)的稳定性最好,初期坝(6~#坝)和战斗坝(5~#坝)的稳定性排在末位。
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 dam(5~# dam) is ranked at the last position among the 10 dams in a uranium tailings pond.
