| 中文摘要: |
| 为研究降雨和地震对露天矿边坡变形的影响，本文基于刚体极限平衡法，利用GeoStudio软件进行不同工况条件下的稳定性分析。结果表明：在自重+地下水、自重+降雨、自重+地震三种工况下对排土场边坡进行稳定性计算，排土场最危险滑面是圆弧形，计算结果均满足规范要求，边坡整体稳定性较好。研究成果可为该类边坡的灾害防控提供理论支撑。 |
| 英文摘要: |
| To study the effects of rainfall and earthquakes on the deformation of open-pit mine slopes， stability analysis was conducted under different working conditions using GeoStudio software based on the rigid body limit equilibrium method. The results show that under three working conditions of self weight+groundwater， self weight+rainfall， and self weight+earthquake， stability calculations were conducted on the slope of the waste disposal site. The most dangerous sliding surface of the waste disposal site is a circular arc， and the calculation results meet the requirements of the specifications. The overall stability of the slope is good. The research results can provide theoretical support for disaster prevention and control of such slopes. |
