FLAC^(3D)模型interface法向应力的MATLAB处理

Post-process of Interface Normal Stress in FLAC^(3D) Model with MATLAB

采矿工程领域经常用到FLAC3D软件进行工作面开挖、巷道支护以及边坡稳定性的研究,但FLAC3D在后处理有关力时仅能出云图。针对FLAC3D在后处理功能中的缺陷,利用MATLAB在数据可视化方面的优越性,通过用FLAC3D自带的fish语言提取相应结构的应力,特别是interface上的法向应力,并运用MATLAB将提取的应力用三维网格展现出来,可以为FLAC3D后续分析提供重要价值。

FLAC3Dis usually used to study the working face excavation,roadway support and slope stability in mining engineering,how- ever,the FLAC3D can only display the force in the cloud while post-processing. For this defects of FLAC3D ,using the advantages of MATLAB in data visualization,the corresponding stress of the structure especially the normal stress of the interface was obtained by the fish language of FLAC3D ,and MATLAB software was used to express the extracted stress with three-dimensional grid,which could pro- vide important value for analysis the FLAC3D result.
