山东省枣庄市中心城区三维地质模型建立研究

目前,直接基于钻孔构建三维地质模型的研究中存在钻孔难于获取、产状信息分布稀疏、建模结果难以人工交互干预等问题,该文以山东省枣庄市中心城区三维地质建模为例,提出一种基于剖面单元格,借助平面地质图添加虚拟钻孔的三维地质体建模方法,实现了基于平面地质图添加虚拟钻孔方式生成精准的剖面图。该方法不仅为解决当前建模中存在的数据不足、建模自动化程度较低及精度不够的问题提供了新的思路,扩大了三维地质建模可利用的数据源,实现了三维地质模型构建,为进一步实现钻孔、剖面与平面地质图数据融合进行模型优化和逐步求精打下了基础,为今后开展三维地质建模工作提供了参考。

Research on Construction of 3D Geological Model at Central Urban District of Zaozhuang City,Shandong Province

At present, there are a lot of problems in modeling directly based on geological drilling, including the difficulty to obtain boreholes, sparse distribution of occurrence information and difficulty in manual interactive intervention of modeling results. In order to solve those problems, this paper put forward a molding method based on section cell using virtual borehole depends on the planar geological map.The results of this study, achieved a plan to add virtual borehole based on improved accuracy profile cell geological block. This method not only provides a new way to solve the existing modeling of insufficient data modeling, low degree of automation and accuracy is not thick, expand the threedimensional geological modeling can use the data source, realize 3D geological model construction, for the further implementation of the multisource data (drilling, geophysical profiles, etc.) fusion model optimization and stepwise refinement to lay the foundation, provide a reference for the future expansion of 3D geological modeling.
