基于SURPAC的FLAC^(3D)三维模型自动构建

Automatic Generation of FLAC^(3D) Model Based on SURPAC

为了将岩土工程分析软件FLAC3D在数值计算方面的独特优势和矿山工程软件SURPAC在三维建模方面的优势相结合.研究了2种软件单元数据之间的关系,提出数据之间的转换方法;采用Fortran语言编制了SURPAC-FLAC3D的接口程序,并通过某大型铁铜矿区建模实例说明程序实施的具体步骤.结果表明:提出的转换方法以及相应的接口程序能够实现SURPAC模型到FLAC3D模型的转换,使FLAC3D建模快捷化,拓展了FLAC3D和SURPAC的应用空间.

A FORTRAN computer language program was written to translate models created in SURPAC, a mine-engineering application, into a form usable in FLAC^3D, a geo-technical anal- ysis application. SURPAC is useful for creating three-dimensional models while FLAC^3D excels in computation speed. Data elements used in the two pieces of software were analyzed. A method to automatically perform the translation from one to the other was proposed. A model representing a goal in one large iron and copper mine was shown to illustrate the method. The results shown that the model built with SURPAC can be translated into a FLAC^3D model. This allows the greater computational power of FLAC^3D to be used and extends the utility of both programs.
