摘要: 以某大型露天矿边坡工程为背景,应用改进的极限平衡理论,建立MSARMA边坡稳定性计算模型,计算边坡安全系数并开展不同因素影响下边坡敏感性分析。依托GIS平台和三维可视化技术手段,构建该露天边坡三维可视化工程地质模型,将边坡稳定性安全系数导入GIS平台,利用空间插值、数据叠置等手段对该露天矿边坡进行三维可视化风险性分区。应用以上计算方法及信息化手段,得出了边坡稳定性计算数据、动态曲线,以及边坡三维可视化分区图像,多角度、多维度地实时反映该露天矿边坡安全稳定状况。

Abstract: With slope project of a large open-pit mine as background,slope stability calculation models of MSARMA are built based on the modified limit equilibrium theory,to calculate the slope stability coefficient and analyze the slope sensitivity analysis under different factors.Relying on GIS platform and three-dimensional visualization technology,the three-dimensional visualization geological models of open-pit mine slope are built.Then,the stability coefficient is imported into GIS platform,and the spatial interpolation,data overlaying technologies are adopted to get three-dimensional visualization zoning of the slope.With the application of methods above and informational ways,the stability calculation data,dynamic curves,and three-dimensional visualization zoning images of the slope are achieved,so as to present the open-pit mine slope stability condition through multi angles and multi dimensional ways.

Key words: Modified limit equilibrium theory, Slope,Stability, Three-dimensional visualization, Risk zoning
