摘　　要：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 user-friendly and can be extended to complex underground engineering applications,improving the efficiency of BIM model generation and ANSYS structural calculation and analysis.
