摘要
复杂三维地质体模型的建立一直是FLAC3D软件前处理过程中的一个难题。因此,提出以Surfer软件为过渡平台,通过对地表及岩层分界面三维地质信息的提取、转换,并将Surfer输出的数据经由FLAC3D软件内嵌的Fish语言编制的程序的二次转换,生成FLAC3D软件可以直接读取的模型数据文件,从而实现了该软件前处理过程中复杂三维地质模型的快速、准确建立。同时结合工程实际,检验了该方法的可行性和仿真效果,结果表明,建模过程简捷、实用,可操作性强,是FLAC3D软件前处理的一种新方法。
Digital modeling of complex three - dimensional geological body is always a difficulty in pre - processing of FLAC^3D. Therefore, a new modeling method is put forward in this paper. The three - dimensional geological information of ground surface and strata interfaces are extracted and transformed in the Surfer software. Using Surfer as a transitional platform, the information can be exported from Surfer and then is retransformed by program made by Fish language embedded in FLAC^3D. According to above process, the model data for FLAC^3D is generated and complex three - dimensional geological model can be created quickly and accurately in pre - processing of FLAC^3D. The feasibility and simulating effect of the method is verified by combining practical project. The result shows that the modeling method is simple, practical and with better maneuverability. Thereby the method is a new, good approach in pre -processing of FLAC^3D.
