【摘要】 在排土场堆排过程中随着高度的增加,基底软岩与排土场内部塑性变形及破坏区增大,文中应用三维数值模拟方法对排土场内部与基底应力场演变规律进行了分析,据此确定其破坏模式。在此基础上应用滑移场理论方法对滑移面进行了搜寻,将两者对比确定滑面,并进行稳定性评价,由此提高了排土场安全评价的可靠性,以确保矿山全安生产。更多还原

【Abstract】 Plastic deformation and failure zone are increased as heaping height raises during waste dump heap,changing law of stress field for base and internal rock mass is analyzed by numerical simulation,and failure mode is insured.Sliding face is probed by using critical sliding theory,sliding face is insured by comparison two method,therefore,reliability of waste dump evaluation is raised,and safe production is provided.更多还原
