基于SURPAC的复杂地质体FLAC^(3D)模型生成技术

FLAC^(3D) modeling for complex geologic body based on SURPAC

针对FLAC3D软件在复杂地质体模型构建及单元网格划分等前处理问题上存在的不直观、工作量大等不足,提出了一种新型的基于SURPAC软件的直观、快速的FLAC3D模型生成技术。在利用SURPAC软件构建地质体块体模型的基础上,将模型以数据文件的形式输出,然后对输出的数据文件运用ACCESS数据库进行处理,形成FLAC3D命令流,再将命令流调入FLAC3D软件中执行,从而实现了FLAC3D的直观、快速建模。该建模方法在广西大厂铜坑矿的空区稳定性分析建模中得到了实际应用,结果表明该方法是完全可行的和有效的。

Aiming at the disadvantages of FLAC^3D modeling, such as the modeling process is not intuitionistic and mesh generation has great workload, a new kind of modeling method is proposed based on SURPAC software. On the base of building SURPAC block model of the complex geologic body, the SURPAC block model data in the manner of data file are exported and processing it using the Access database; and then the modeling order flow is generated and to run the order flow in FLAC^3D to construct the FLAC^3D model automatically and fleetingly. The new FLAC^3D modeling method has been used in building the cavity stability analysis model of Tongken Copper mine in Guangxi Autonomous Region; and the result shows that the new modeling method is feasible and effective.
