| 摘 要： | 在桓仁矿业有限公司选矿厂尾矿坝现场勘察的基础上,将坝体实测主轴剖面进行合理地概化和延伸,建立有限元数值模型,对处于正常运行条件下的坝体进行数值分析,揭露坝体内部应力状态,同时在数值分析结果的基础上,采用基于极限平衡理论的条分法对尾矿坝的稳定性进行计算,从而实现了对尾矿坝稳定性的定量分析,对尾矿库的安全生产具有重要的指导意义.

| Abstract: | On the basis of the on-the-spot investigation about tailing dam of Huanren Mining Concentration Plant,the finite element numerical model is built through reasonable generalizing and extending the actual principal section of the dam.Then,the tailing dam in a existing state is analyzed for exposing the stress condition in the dam,at the same time,the stability analysis of the tailing dam is proceeded through the slice method based on the limiting equilibrium theory to realize the quantitative analysis of the ... |
