- 摘要:
- 为系统分析排土场在静动力条件下的变形规律和破坏模式，全面科学评估排土场的安全稳定性，以某露天矿山排土场为研究背景，分别应用极限平衡法和有限单元法进行数值模拟分析，研究排土场在复杂受力和边界条件下的静态变形特征以及地震作用下的动力稳定性。研究结果表明：在静力条件下排土场总体剪应变较小，剪应变分布区域远离坝坡，整体稳定性较好。在6级地震载荷影响下，排土场最大永久变形量较小，较大动剪应变分布区域远离坡体，不会造成边坡失稳。研究结果可为排土场边坡稳定性分析提供参考。
- Abstract:
- In order to systematically explore the deformation laws and failure modes of the waste dump under static and dynamic conditions,and comprehensively and scientifically evaluate the safety and stability of the waste dump,this study takes the waste dump of an open-pit mine as the research background.The limit equilibrium method and the finite element method are respectively applied for numerical simulation analysis to investigate the static deformation characteristics of the waste dump under complex stress and boundary conditions,as well as its dynamic stability under seismic action.The results show that under static conditions,the overall shear strain of the waste dump is relatively small,and the shear strain distribution area is far away from the dam slope,indicating good overall stability.Under the influence of a magnitude 6 earthquake load,the maximum permanent deformation of the waste dump is small,and the area with large dynamic shear strain is far away from the slope,which will not cause slope instability.The research results can provide a reference for the slope stability analysis of other waste dumps.
