MSC.PATRAN工程地质三维建模技术研究

Study on Method of 3D Modeling of Engineering Geology by Software MSC.PATRAN

以某一深埋洞室为例,探讨了采用MSC.PRTRAN软件进行三维实体几何建模并划分网格的方法以及模型导入FLAC3D的软件的过程,分析了其中技术难点,针对复杂地表面的拟合、岩土体的开挖、地下水位面的创建等问题,提出了行之有效的处理方法。实践证明,相比其他软件,MSC.PRTRAN软件操作界面更友好,建模效率高,易入门。

In the case of some deep buried tunnels ,the method of 3D modeling of engineering geology by software MSC.PATRAN was discussed ,the process of 3d model imported to flac3d software was also involved .For complex sur-face fitting,rock and soil mass excavation and generation of groundwater level etc ,some effective treatment was put for-ward.The practice shows that ,MSC.PATRAN has an more friendly operation interface and higher efficiency in 3D mod-eling of engineering geology compared to other tools ,these features make it easy to start with .
