摘　　要：本文以钻孔资料为源数据,利用VTK强大的数据处理与图形显示功能,使用规则格网三棱柱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。The regular grid triangular prism model was used to build 3D stratum based on borehole data, in which visualization function of VTK for data processing was used. This model could provide controlling operation including strata move, rotation, zooming and transparence. Besides, the analytical functions of arbitrary strata point inquiry, arbitrary slice cutting and attribute inquiry could be realized. In this way, the real case could be simulated, and the authenticity of 3D stratum should be enhanced. The relevant application has proved that this method is useful and reasonable.
