虚拟现实技术在露天矿边坡工程中的应用

露天矿边坡工程是集工程勘察、分析计算、施工和监测等多阶段、多元维数据分析于一体的复杂的系统工程。随着开采进行，边坡揭露和勘察获得的地质数据与工程数据复杂程度与日俱增，传统二维图纸很难表达清楚这些数据之间的关系，这就迫切需要把这些多元数据融合分析与三维可视化，以便领会复杂数据，实现科学决策。结合多种边坡工程数字化勘察手段，以东北大学虚拟现实平台为基础，建立了三维地质模型、工程模型等虚拟场景与集成勘探数据、分析计算成果和治理措施的具有数据查询和交互控制于一体的虚拟现实系统。以司家营铁矿东帮边坡工程为例，实现对边坡工程勘察、现场工程和分析计算等多元数据的融合分析与虚拟可视化，达到评价露天矿边坡稳定性和科学决策的目的。

Application of the Virtual Reality Technology in Open-pit Slope Engineering

Open-pit mine slope engineering is a complex system engineering of relating to the analysis of multi phase and multi dimensional data，such as engineering investigation，analysis and calculation，construction，and monitoring.With the development of mining，the geological information and engi-neering information from slope exposing and engineering investigation become more and more complex，which makes it difficult to clearly describe the relationship among all these data though the traditional 2D maps.Therefore，it is urgent to make multi-data fusion analysis and 3D visualization，in order to understand the complex data and make a scientific decision.Combined with digital prospect of slope engineering and based on the virtual reality system platform of Northeastern University，a virtual reality system is formed，in which the virtual scene includes 3D geological model and engineering model，and the reality system owns the database query and interactive control function on the exploration data inte-gration，analysis of calculation results，and the measurement.Taking the eastern slope of Sijiaying Iron Mine as a case，its multi-data fusion analysis and virtual visualization of engineering prospection，field investigation and calculation can be realized to reach the goal of evaluating the open-pit slope stability and decision-making.
