摘要
空间数据模型是地质体三雏构模的关键,根据地质体的几何特征,建立了适用于连续型地质体的数据模型,构造了三棱柱类,提出了相应的数据概化方法,开发了柱体构模技术和地质体三雏可视化构模系统。利用该系统,建立了某人工围湖工程的三维可视化模型,验证了构模技术的适用性。
Spatial data model is the key to building 3D model of geological body. According to the geometry characteristics of geological body, a suitable spatial data model is put forward, and pillar modeling technique is developed. And the modeling system of continuous geological body is also developed. As an example, the 3D visual model of the embankment engineering of one artificial lake is built by the visual modeling system.
