| 中文摘要: |
| 为研究高陡露天边坡的稳定性，本文以四川省某露天矿石灰岩质边坡为工程背景，选取1个典型剖面分析，运用赤平投影分析法对岩质边坡的稳定性进行分析评价，并采用强度理论的刚体极限平衡法与二维有限元数值模拟、三维数值模拟等进行了相互验证比较分析。研究结果表明：1个典型剖面在3种工况下的整体边坡安全系数均符合规范要求值，边坡整体稳定性较好。所得结论对后期施工设计提供了理论依据及数据支持，同时为类似工程的边坡稳定性分析提供了参考。 |
| 英文摘要: |
| In order to study the stability of high and steep open-pit slope， taking the limestone slope of an open-pit mine in Sichuan Province as the engineering background， a typical profile analysis was selected， and the stability analysis and evaluation of rock slope were carried out by using the stereographic projection analysis method. The rigid body limit equilibrium method of strength theory， two-dimensional finite element numerical simulation and three-dimensional numerical simulation were used to verify and compare each other.The research results show that ：The overall slope safety factor of a typical section under three working conditions meets the requirements of the specification， and the overall stability of the slope is good. The conclusions obtained provide theoretical basis and data support for the later construction design， and provide reference for the slope stability analysis of similar projects. |
