地质剖面图中复杂断层的自动生成方法

Automatic generation of complicated fault in geological section

为实现地质剖面图中复杂断层的自动生成,通过分析断层数据类型,实现断层数据规范化处理;分析断层自身的基本要素(断点、断距、性质、走向、倾向、与地层的切割、错动关系等),提出采用"复原法"构建单一断层模型的方法;依据复杂断层的空间拓扑关系及其重要性,划分断层级别,理顺断层之间、断层与地层之间的关系,探索出地质剖面图中复杂断层的自动生成方法。通过开滦某煤矿的地质数据验证了该方法的有效性。该方法可依据用户需要,生成任意方向的地质剖面数据,为基于剖面的三维建模提供了充足的原始建模数据。

The simulation and expression of complicated faults is an essential technique in automatic generation of geological section.The researches of this paper are the basic theories and essential techniques of simulating complicated faults;and a series of approaches are proposed.Based on the practical geological exploration,data types are analyzed and normalized database is designed.The strata recovering technique is presented to simulate single fault.Based on topological relations between faults,the levels of complicated faults are divided.According to the levels,the relationships of strata and strata,strata and faults,faults and faults are determined.The geological sections can be generated automatically.In order to confirm the practical result of this method,some automatically generated sections containing complicated faults are presented.
