摘　　要：为解决由于褶皱岩体的边界面可能是非单值曲面给三维构模带来的困难,根据褶皱岩体的几何特征,提出了适合于褶皱岩体构模的数据模型,建造了面向对象的数据结构,开发了断面构模技术与三维可视化构模系统,并利用该系统建立了抚顺西露天矿北帮边坡岩体三维可视化模型。The characteristics of nonmonodromy of folded surface has brought great difficulties for 3D modeling of folded rockmass. According to the geometrical characteristics of folded rockmass, a suitable spatial data model is put forward for folded rockmass, and the corresponding data structure is built. Based on these, section modeling technique and visual modeling system are developed. Using this modeling system, 3D visual modeling of north slope in Fushun west openpit is built.
