复杂地质体的3DEC快速建模

3DEC Rapid Modeling of Complex Geologic Body

复杂地质体的快速建模技术一直是岩土工作者所关注的问题,基于Surfer软件和Fish编程语言实现了3DEC软件快速建模,克服了3DEC在前处理方面的不足。通过3DEC内嵌的Fish语言进行编程,将Surfer差值后生成的文件转化为3DEC可读数据文件,实现了复杂地质体的快速建模,在河北某金属矿山复杂地质体建模中的实际应用结果表明,其能够快速有效地建立复杂地质体模型,为3DEC快速建模提供了一种新途径。

The rapid modeling of complex geological body is al- ways a issue that is concerned by researchers. This paper intro- duces a new method to achieve the rapid 3 DEC modeling of com- plex geologic body based on Surfer and Fish, overcoming the dis- advantages of 3DEC in pre -processing. First, Surfer is used to establish a model with regular grid and export data files which contain the information of complex geologic body, then, by pro- gramming with Fish language embedded in 3 DEC, the Surfer data file is transformed to that can be read by 3DEC. Finally complex three -dimensional geological model can be created quickly and accurately. This method has been used in the modeling of com- plex geologic body for an iron mine in Hebei province, and result shows that the method is feasible and effective in modeling of complex geologic body, providing a new approach for 3DEC rapid modeling.
