Abstract: BIM technology is a new design approach, which implements the design change from two-dimensional to three-dimensional space, from static information to dynamic information technology development. On the basis of seeing a lot of domestic and international research literatures on supporting design of deep excavation engineering, summarize the design methods; analyze of the advantages and disadvantages of different design software and critical theoretical issues of design methods; propose the idea of BIM technology which application in the supporting design of deep excavation engineering; analyze of the key technical issues on BIM technology application in the supporting design of deep excavation engineering, which provide reference for relevant research.
