基于GIS的太原市活断层三维建模

针对目前三维地质建模技术不能真实反映实际地层与复杂结构面相互交切关系的综合三维特征信息,本文提出了一种在ArcGIS环境下了利用浅层地震探测资料构建三维地层和断层模型的新方法,该方法通过对浅层地震探测深度剖面进行"微分",设计构建了三维地质模型的算法,利用AOVBA开发方式进行了程序的开发,对太原市活断层探测区域第四纪地层剖面和断层断面进行了三维地质可视化建模。

3D geological modeling of taiyuan active fault surveying based on GIS

According to the comprehensive three-dimensionalinformation of current three-dimensional geological modeling technology which can not reflect the actual formation and complex structure plane intersection relationship, this paper proposes a new method in ArcGIS environment for constructing three-dimensional stratum and fault model by using shallow seismic search data, which is through the "differential" of shallow seismic exploration depth sections, and the design constructs the three-dimensional geological model algorithm, using AOVBA development mode to develop the program, for Taiyuan city active fault detection in Quaternary stratigraphic section and fault section area to program 3D geological visualization modeling.
