Abstract: This article is a preliminary analysis about the escape evacuation simulation and systematic analysis of the architectural BIM model by escape simulation software. By loading the escape path and setting the number of evacuated people, the software can got the evacuation time, evacuation trajectory, and evacuated the port number of the graph and regional changes in the number graph contribute to architects targeted adjustment and optimization to design. By research, we learned that not only to study BIM technology applications to understand and research, but also to find better ways to in the design service.
