摘　　要：在AutoCAD平台下完成露天矿DTM曲面构建,采用三角剖分算法基于线框模型构建地表模型及二次境界模型,并求取它们的交线。以此交线剪切地表及二次境界线框模型,组成含有地形线的终了境界线框模型,实现三维可视化模型的建立。构建应用菜单,编制应用程序,最终实现露天矿终了境界中DTM曲面构建及其运算的程序化。本研究成果在降低误差的同时提高设计的精度和工作效率,对于露天矿终了境界设计图绘制具有重要的意义。The DTM surface construction of the open-pit mine was completed under the Auto CAD platform,and the surface model and the secondary boundary model were constructed based on the wireframe model by using the triangulation algorithm,and their intersection lines were obtained.Based on the intersection line shear surface and the secondary boundary line frame model,the final boundary line frame model with terrain line is formed,the establishment of three-dimensional visualization model is realized,Build application menus,compile application programs,and finally realize the programming of DTM surface construction and operation in the finel realm of open-pit mines.It is of great significance to improve the accuracy and efficiency of design while reducing the error for drawing the final boundary design map of open-pit mines.
