PURPOSES : In this study, a Design Support Automatic Program for NATM (new Austrian tunneling method) tunnels based on BIM that can generate shape information including property information via the development of BIM libraries and the construction of a library design support automatic program is developed.
METHODS : In this study, the abovementioned program is developed as an add-in Revit program. AutoDesk's program has the highest utilization rate, and it allows support tools to be added easily. Construction information classification based on WBS(Work Breakdown Structure) is developed. Subsequently, library construction and program development algorithms are developed.
RESULTS : The automatic program constructs a library that reflects geometric characteristics through the construction of a library automatic module as well as generates three0-dimensional (3D) shape information by mapping between the constructed library and 3D informal alignment. The proposed program can automatically assemble a constructed library through the development of an algorithm for generating sequences of 3D shape information and automatically place models on a 3D terrain.
CONCLUSIONS : The proposed automatic program can be designed and changed easily. It is expected to contribute to improvements in the speed of 3D NATM tunnel modeling and the efficiency of NATM tunnel design.
