基于AutoCAD的拱形交叉巷道FLAC^(3D)快速建模研究

Research on Rapid Modeling Method of Arch Cross Tunnel FLAC^(3D) Model based on AutoCAD

拱形交叉巷道FLAC3D模型网格建立时要利用FLAC3D中固有的柱形交叉隧道网格(cylint)单元,建立三维网格模型效率较低。针对采矿工程领域的数值模拟计算问题,研究了Auto-CAD平面图形向FLAC3D拱形交叉巷道模型转换的技术,利用AutoCAD建立了拱形交叉巷道FLAC3D模型,并给出了详细的方法与步骤,实现了利用FLAC3D分析拱形交叉巷道工程问题时方便、快捷地建立地质模型。

Establishment of arch cross tunnel FLAC3D model grid needs to use inherent cylindrical cross tunnel grid（cylint） unit in FLAC3D, the process of building three-dimensional mesh model is ineffi- ciency. Aimed at the numerical simulation calculation problem in field of mining engineering, technology of AutoCAD planar graph transform to FLAC3D arch cross tunnel model was studied. Arch cross tunnel FLAC3D model was set up by using AutoCAD, and detailed methods and steps were given. When setting up a geological model for studying arch cross tunnel engineering problems by using FLAC3D, it can hand quickly.
