| 中文摘要: |
| 某露天石灰石矿区设计边坡高达200m,属于二等边坡,为了验证边坡设计的合理性与最终边坡的稳定性。根据矿区地质条件与矿体产状,对矿山边坡进行分区,每区选取一个典型剖面,利用MIDAS GTS进行二维数值模拟。依据非煤露天矿边坡工程技术规范标准对模拟结果进行分析判断,结果表明该边坡设计预留合理,最终境界边坡在三种荷载工况下可以保持稳定,通过数值模拟云图分析,了解边坡最大主应力,最大位移的位置,为矿山开采过程中边坡监测的重点位置,指明了方向。 |

| A certain open-pit limestone mining area is designed with a slope height of up to 200m, which belongs to the second-class slope. In order to verify the rationality of the slope design and the stability of the final slope. According to the geological conditions of the mining area and the occurrence of the ore body, the mine slope is divided into zones, and a typical profile is selected for each zone. MIDAS GTS is used for two-dimensional numerical simulation. According to the technical specifications for non coal open-pit mine slope engineering, the simulation results were analyzed and judged, indicating that the slope design reservation is reasonable, and the final boundary slope can maintain stability under three load conditions. Through numerical simulation cloud analysis, the position of the maximum principal stress and maximum displacement of the slope was understood, which provides a key location for slope monitoring in the mining process and indicates the direction. |
