断层网建模关键技术研究

面对大多数的建模方法主要采用基于多源数据交互的建模方式，需要大量人工交互且不便于计算机自动或半自动化处理等问题，本文引入空间索引和OBB碰撞检测方法来检测断层间的接触关系，使用符合地质规律的测地线进行追踪，采用路径切割方法处理两个地质界面间的线性接触关系，从而自动处理任意断层面间的截切关系，构建复杂断层网。利用某地区作为研究区域，从实际数据出发，构建该区复杂的三维断层网，以验证本文提出的断面接触关系处理技术的有效性。

Research on key technology of fault net modeling

In the face of most modeling methods are based on multi-source data interaction modeling, requires a lot of manual interaction and does not facilitate the computer automatic or semi-automatic processing. In order to automatically deal with arbitrary complex fault cutting relations, this article introduces the spatial index and OBB collision detection method to detect the contact relationship between the faults. In order to conform to the geological laws, the geodesic is used for tracking, and a linear cutting method is used to deal with the linear contact relationship between two geological interfaces. Using a certain area as the research area, based on the actual data, the complex 3D fault system is constructed, to verify the feasibility of the automatic processing method of contact relation between fault planes proposed in this paper.
