基于UDEC的边坡稳定性分析

为了露天矿边坡有更好的治理,为其加固和生产提供理论依据,采用离散元软件UDEC模拟边坡失稳状态,探索边坡失稳的新理论和方法。结果表明:边坡的失稳主要受顺坡向的节理面和F1等断层控制。它在将来某种条件下的失稳破坏并会形成前端整体的滑动破坏模式。随着变形块体的下滑破坏,整体坡段也随之逐渐的失稳破坏说明离散单元法模拟的结果与工程地质特征相吻合,采用离散法模拟边坡失稳是完全可行的,为计算露天矿边坡失稳又增加了一种有效的分析方法。

Analysis of slope stability based on UDEC

To have a better harnessing of the slope of FUSUN open mine side-slopes,we use discrete element software,which is called UDEC to simulate slope instability situation,and search a theoretical basis of slope instability.The results show that the joint surface and the F1 fault of the slope made a major impact on the slope instability and formed the front section damage and slide mode under certain conditions.With the sliding and damage of the deformed blocks,the station of the overall slope was also instable,which means that the simulation results of the discrete element method accord with the engineering geological characteristics.So,the discrete element method is feasible.The open mine side-slopes instability calculation has an another effective method.
