摘　　要：FLAC^(3D)是用于工程力学计算的显式有限差分程序,主要用来解决有限单元法不能企及的大变形问题、复杂非线性行为和不稳定系统等问题,被广泛应用于岩土工程、土木工程和采矿工程领域,但其应力的形象表达等后处理环节还有待提高,而Surfer软件能将三维数据简便快速生成二维、三维图形。针对FLAC^(3D)模型分析结果可视化不丰富的问题,采用FLAC^(3D)内置fish语言提取模型相应变量数据并以Surfer可以读取的格式组织起来,用Surfer进行模型应力的可视化后处理。实例表明,给出的fish语言代码能方便正确地提取数据,Surfer软件生成的底板应力可视化图形能将应力大小与高低对应起来,较形象表达FLAC^(3D)分析数据。FLAC3D is a explicit finite difference program,which were used to calculate engineering mechanics. II also be used in geotech- nical engineering,civil engineering and mining engineering field to solve the large deformation prubiem,the complicated nonlinear be- havior and unstable system,etc, which finite element method cannot solve, but the post-processing such as image expression of stress need to be improved. Surfer software couht generate 2d and 3d graphics from 3d data simply and rapidly. For the problem of little abun- dant visualization of FLAC3D model analysis results, using fish language of FLAC3B extracted the variable data that Surfer needed and or- ganized that data which Surfer can read,Surfer could process that stresses of FLAC3D model visible. The given fish code could extract stresses easily and correctly through a specific example,and the size of stress could correspond to height in the stress graphics generated by Surfer,which expressed the FLAC3D analysis data more readily relate.
