| 摘 要： | FLAC3D是一款优秀的岩土力学分析软件,但其建模效率较低,尤其面对复杂地质条件时,其应用受到一定程度的限制。本文分析了FLAC建模命令的特点,提出一种新的较简单的建模方法,并开发了相应的计算机辅助建模程序,该方法通过坐标变换、复杂边界点坐标均匀化处理、逐列定义子网格坐标,可生成具有复杂边界的地质模型,且便于赋材料参数及应力边界条件参数,有效提高工作效率。 |

| Abstract: | FLAC is the excellent software for rock and soil mechanics numeric simulating,but it does not perform well in modeling,especially to complex geological model,so its application is limited to some extent.In this paper,the modeling commands in FLAC software were analyzed and a new simple modeling method for FLAC was proposed and corresponding computer-aided modeling code was developed.To transform original coordinates of complex boundaries,get the boundaries uniform distributed transversely,and define the coordinates of each sub-grid column by column,then a model with complex boundaries can be built and it is easy to assign the material parameters and geo-stress boundary conditions.Our method can contribute to the numeric simulation of FLAC. |
