| 摘 要： | 以晋宁磷矿露采边坡为例,利用ArcGIS软件建立了边坡三维地层可视化模型,开发了转化插件;从三维地层模型截取典型二维地质断面,导出二维断面地层几何信息及材料信息;利用独立覆盖无网格质点法实现了从ArcGIS地层模型到数值计算模型的自动建模,并对该露采边坡典型断面进行了稳定性分析。应用实例验证了研究方法的正确性、实用性,及其良好的工程应用前景。

| Abstract: | With the slope in Jinning Phosphate Mine as an example, a 3-D geoscience visual model was constructed using ArcGIS geostatistical analyst, from which a 2-D section was cut out by a developed plug-in of ArcGIS, and exported with its geometric information and material information. By using Independent Cover Meshless Particle, the automatic numerical modeling from ArcGIS strata model to numerical computing model was achieved. Based on that, the slope stability analysis was made for the typical section of the slope in open pit. The practical application analysis has verified the validity and practicability of this model, as well as its application prospect in the engineering project. |
