摘要
文章论述了一种在AutoCAD平台下建立露天矿三维地质模型的方法。以图形单元作为建模要素,采用顾及台阶属性Delaunay三角网凸包算法建立界面模型,通过面域拉伸和实体布尔运算等方法生成三维矿模。研究结果表明,该方法不仅能达到逼真的三维动态效果,而且对于边坡稳定性分析更为准确方便,有助于露天矿的日常生产和管理。
This article elaborates one method of establishing 3-D engineering geological model of the open pit based on the AutoCAD platform.Taking the graphics unit as the modelling essential factor,considering the bench attribute establishes the surface model by Delaunay triangular net convex hull algorithm,and generates 3-D engineering geological model by surface stretch and solid Boolean calculation.The research results demonstrate that this method not only can achieve the lifelike 3-D dynamic effect,moreover,it is more accurate and convenient for the slope stability analysis and helpful for daily production and management of the open pit.
