摘要

三维地质建模是地质数据可视化和空间分析的关键技术之一。针对传统建模方法建模速度慢、建模效率和精度较低的问题，提出了一种直接基于钻孔的点→线→面→体快速递进三维地质建模方法。该方法先对钻孔地层信息进行人机交互对比构成地质剖面，再按钻孔实际坐标在三维空间中还原地质剖面的实际位置，接着通过对剖面间的地层连线进行Kriging插值，形成一系列地层面模型，然后以此为基础构建三维地质框架模型，最后利用BSP矢量剪切技术来裁剪模型边界，形成研究区三维地质模型。该方法在福州市上街镇三维城市地质模型构建的实际应用中得到了验证。实践结果表明，该方法不仅可以实现三维地质模型的快速构建，还可以显著提高三维地质模型的精度。

Abstract

The 3D geological modeling is one of the key technologies in spatial analysis and visulization of geological data. To improve the speed

efficiency and accuracy of geological modeling

a fast progressive 3D geological modeling method (FPGM) from point to line to surface to body with borehole data has been proposed in this paper. Firstly

the geological profiles are constructed with strata data of boreholes by human-computer interaction

then the real positon of geological profile is restored in 3D space according to the coordinates of the boreholes. After that

using the same strata lines in sections

a series of strata surfaces model are constructed by Kriging interpolation. Based on the steps above

the frame model would be accomplished. Finally

the binary space partitioning (BSP) vector shear technology is adopted to cut the boundary of the model

thus a 3D geological model of study area is constructed. This method has been applied to the construction of 3D geological modeling in Shangjie Town

Fuzhou city

showing that this method can not only realize the fast construction of 3D geological model but also improve the accuracy of the model remarkably.
