| 摘 要： | 本文以钻孔资料为源数据,利用IDL语言强大的数据处理与图形显示功能,分别使用多层DEM表面模型法和实体模型法构造地层三维模型,实现了地层的平移、旋转、缩放、透明等多种控制操作。并实现了任意点地层分布查询、任意剖面切割、属性查询等分析功能,从而尽可能模拟现实世界,增强三维地层的真实感。最后,将其应用于实际工程中,验证了其合理性和实用性。

| Abstract: | The multi-surface model and volume-based model of strata are built based on borehole data,in which visualization function of IDL language for data processing is used. These models can provide controlling operation for strata move,rotation,lessening,enlargement and transparence. Besides,the analytical function of arbitrary strata point inquiry,arbitrary slice cutting and attribute inquiry can be realized. In this way,the real case can be simulated,and the authenticity of 3D stratum should be enhanced. The relevant application has proved that this method is useful and reasonable. |
