摘　　要：从堤坝设计、施工、管理的角度,建立了重影点定位消隐的数学模型,确定了空间点与面、面与面之间的隐藏关系。在此基础上,利用VC++可视化编程技术,实现了堤坝三维透视图的消隐。结果表明,该方法数据结构简单,克服了传统的透视图消隐数学模型计算量大、计算复杂等不足,为地形地物透视图的消隐提供了新的方法与手段的支持。The hidden-removal mathematical model of ovedapping point location is generated and the hidden relationship between point and plane, plane and plane in space is set up with respect to dam design, construction and management. On this basis, it generates the hidden removal of the three-dimensional dam perspective drawing with VC ＋ ＋ visualizing program technology. The result shows that these simply illustrated data construction approaches overcome traditionally considerable and complicated calculation disadvantages etc. It also provides new methods and supporting means for bidden-removal of the surface features and ground objects＇ perspective drawing.
