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.
