Abstract:

In order to promote the application of BIM technology to the design and construction of tunnels constructed by New Austrian Tunneling Method(NATM), the parametric modeling of primary support components is carried out. The characteristics of bolts, small conduits, grille steel frames and other primary support components in the process of tunnel design and construction are studied; Revit is used to carry out secondary development; the parametric modeling method of tunnel components is studied; and a plugin which can realize rapid modeling and automatic layout of primary support is developed by improved algorithm. The study results show that the secondary development of Revit can apparently improve the efficiency of primary support component modeling of tunnel constructed by NATM, and has a good applicable effect to the actual modeling process.

Key words: New Austrian Tunneling Method(NATM), primary support components, BIM, Revit API, parametric modeling, automatic layout
