摘要：The
emergence of Open BIM effectively improves the interoperability of building information.
Besides, cloud technology supports virtualization and QoA (Quality of
Assurance) in the case of the distributed system and multi-user collaboration.
Based on the cloud and the Open BIM, this paper puts forward the cloud services
models and the cloud-based Open BIM building information interaction framework,
and further illustrates the architecture of cloud deployment pattern and the
information interaction process. Finally, the paper takes underground rail
transit project as example and explains how to deploy and implement the tunnel
construction management platform.
