Shield tunnel structure information modelling method based on building information modeling technology
为解决隧道工程建设各阶段之间的信息交流和数据共享困难的问题,前期在工业基础类(industry foundation classes
简称IFC)标准的基础上实现了盾构隧道建模数据模型。在此基础上,提出基于建筑信息模型(building information modeling,简称BIM)技术的盾构隧道结构信息模型建模方法。根据扩展的盾构隧道结构信息模型的IFC表达,提出了单个管片块建模方法和隧道线路解算流程和步骤。在此基础上,进行盾构管片拼装与隧道建模,建立了盾构隧道建模流程和参数化建模方法,形成了基于BIM技术的盾构隧道结构信息模型建模方法。最后,通过实例验证了建模方法的可行性。工程应用表明,通过借鉴和引入BIM技术,建立基于统一IFC数据标准的盾构隧道结构信息模型,可以实现盾构隧道信息的无损交换与充分共享,从而进一步验证了前期提出的基于IFC的盾构隧道建模数据模型的正确性。研究成果可为隧道数值计算分析提供初始模型,为实现隧道三维可视化模型和分析计算模型的无缝对接提供基础。
Abstract
With the purpose of solving the problem of model sharing among stages of shield tunnel construction
an IFC-based data model of shield tunnel was built in previous research. Based on the IFC-based data model
a BIM-based shield tunnel structure information modelling method is introduced in this paper. According to the extended IFC description of shield tunnel information model
the modelling method of single segment and flow and process of tunnel axis are proposed. Based on this
a shield tunnel assembling method is built
as well as a flow chart and a parametric modelling method of shield tunnel. By this way
the BIM-based shield tunnel structure modelling method is formed. The modelling method is examined by applying it to a metro shield tunnel case. The research shows that
by introducing the concept and technology of BIM
it is suitable for the communication and sharing of the information of shield tunnel structure that builds the shield tunnel structure information model based on the uniform IFC standard. The validity of the IFC-based data model of shield tunnel is verified further. The result in this paper can provide the initial model for numerical calculation and analysis
and provide foundation for realizing seamless connection of visualization model and analytical model.
