通过对IFC基础数据格式到APDL命令流数据类型的框架分析与模型对应，从坐标信息、截面参数、材料属性、单元类型、关键点和线面体数据等方面解析两者的对应过程，提出一种沉管隧道工程参数化BIM模型向ANSYS有限元模型快速生成转换方法，通过C#程序设计语言开发沉管隧道参数化一键生成IFC模型和对应的APDL命令流软件。主要结论如下： 1) 参数化生成的IFC格式隧道模型可在BIM Vision等查看，模型可提交至施工运维方进行后期模型的有效利用； 2)通过修改隧道尺寸参数一键生成对应的IFC模型和划分好网格的APDL命令流模型，可节省相关设计人员95%的建模时间； 3)设计人员可对生成的APDL命令流进一步修饰，开展隧道结构静力计算、模态计算、动力计算等分析，分析结果可有效指导工程设计； 4)集成的参数化建模软件客户端操作方便，可推广至复杂地下工程使用，提高BIM模型生成和ANSYS结构计算分析效率。
By analyzing
the framework and model correspondence between the IFC and the APDL command,
the corresponding process of the two is analyzed. A rapid transformation method
from tunnel engineering parameterized BIM model to ANSYS finite element model
is proposed, the software was developed by using C# programming language. The
main conclusions are as follows: (1) The generated IFC model can be viewed in
BIM Vision. The model can be submitted to the construction and operation party
for effective utilization; (2) By modifying the tunnel size parameters to
generate the corresponding IFC model and the APDL command flow model, 95% of
the modeling time is saved; (3) Designers can further modify the generated APDL
command stream to conduct static, modal, and dynamic analysis of tunnel
structures. The analysis results can effectively guide engineering design; (4)
The integrated parameterized modeling software is userfriendly
and can be extended to complex underground engineering applications, improving
the efficiency of BIM model generation and ANSYS structural calculation and
analysis.
