Abstract:

In the paper, the technology of using structural model database to assemble tunnel is proposed, the classification of tunnel structure model database is presented, and the parameters of each structural model is designed. The specific processes of 3D tunnel model building with 6 functional groups are presented. The input and output requirement and the effect of each group are analyzed. In the end, the prospects of the development of 3D tunnel design software are proposed.

Key words: tunnel modeling, digital tunnel, 3D design
