摘要
有限差分方法(FDM)是计算机数值模拟最早采用的方法之一,至今仍被广泛运用。FLAC3D就是基于显式有限差分法的岩土工程数值模拟软件,其在岩土方面的实用性已得到许多同行的认同,但在前处理功能上尚有欠缺。结合泉州至三明高速公路三明市境SMA6合同段桃源A匝道AK1+540~AK1+620边坡实例,利用通用有限元程序ANSYS的强大前处理功能和FLAC3D在处理岩土工程方面的优势,在ANSYS中进行建模及网格剖分,导入FLAC3D计算,得出边坡的稳定性状况,为边坡的设计施工提供参考。
Finite difference method of one of the oldest numerical simulation methods,and it is used far-ranging recently.FLAC3D is geotechnical engineering numerical simulation software based on the finite difference method.Many experts use the program when they want to solve problems relate to rock and soil.By using the great preprocessed function of ANSYS and the superiority of FLAC3D,the stability analysis on the Quanzhou-Sanming road slope is put forward,and the result can be used for design and construction.
