基于Surfer平台的FLAC3D 复杂三维地质建模研究

复杂三维地质体模型的建立一直是FLAC^3D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FLAC^3D软件内嵌的Fish语言编制的程序的二次转换,生成FLAC^3D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FLAC^3D软件前处理的一种新方法。

SURFER SOFTWARE PLATFORM BASED COMPLEX THREE - D IMEN2 SIONAL GEOLOGICAL D IGITAL MODELS FOR PRE - PROCESSING OF FLAC3D

Digitalmodeling of comp lex three - dimensional geological body is always a difficulty in p re - p rocessing of FLAC^3D. Therefore, a new modelingmethod 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 p latform, the information can be exported from Surfer and then is retransformed by p rogram made by Fish language embedded in FLAC^3D. According to above p rocess, the model data for FLAC^3D is generated and comp lex three - dimensional geologicalmodel can be created quickly and accurately in p re - p rocessing of FLAC^3D. The feasibility and simulating effect of the method is verified by combining p ractical p roject. The result shows that the modeling method is simp le, p ractical and with bettermaneuverability. Thereby the method is a new, good approach in pre - processing of FLAC^3D.
