针对目前隧道动态设计信息管理仍然只是从不同数据类型和结构方面进行设计的现状，为避免因数据异构性而造成的信息共享困难，实现隧道工程全生命周期信息数据共享与交换的完整性和有效性，阐述了IFC标准扩展的方法，并依据现有IFC标准对建筑领域的描述方法，选取隧道结构为研究对象，从隧道空间结构、物理元素和属性集合等方面出发，实现IFC标准在隧道领域的扩展，扩充了IFC标准的数据描述领域.在此基础上，借助Revit建模软件，开发了参数化隧道反馈分析模型，进而形成了完整的隧道动态设计信息集成模型的创建流程及方法.验证结果表明，基于该方法能够建立一种较为完善的隧道动态设计信息集成模型.所建集成模型已成功应用于隧道动态反馈分析管理系统.

In view of the current situation that  dynamic design information management of tunnels is still designed only from different data types and structures,in order to avoid the difficulty of information sharing caused by data heterogeneity to realize  the integrity and validity of information data sharing and exchange in the whole  life cycle of tunnel engineering,this paper  expounded the method of IFC standard expansion, and based on the existing IFC standard to select the tunnel structure as the study object, and the IFC standard was expanded in tunnel field from the aspects of tunnel spatial structure, physical elements and attribute set,and the data description field of IFC standard was expanded. On this basis, the parameterized tunnel feedback analysis model was developed by using the Revit software, then, a complete process and method for building information integration model of tunnel dynamic design have been completed. The validation results show that a more perfect information integration model of tunnel dynamic design can be established based on this method. The proposed integrated model has been successfully applied to the  dynamic feedback analysis management system of tunnels.
