Design of tree
topology cavern project often faces the challenges of multidiscipline,
multipipeline, multiintersection,
multisection, etc.
Relying on a cavern project, the main points of building information
modeling (BIM) technology are summarized, and through Revit and Navisworks
software platform, 3D modeling technical route and process of cavern project
are sorted out and defined. The 3D modeling method of some complex structures
like parametric arch ring, room joint and Yjoint is
mainly studied, which solves the problems of mismatch between pipeline and
reserved buried pipeline, conflict between buried pipeline and bottom pit, and
pipeline passing stress component of vault. The practical results show that:
(1) The efficiency of section selection in digital design is greatly improved
by realizing a family of common arch contour parameterization. (2) The
visualization characteristics of BIM software and the principle of collision
interference check provide theoretical support for the selection of complex
structures such as room joints and Yjoint, and
effectively avoids design error and omission. (3) Based on the geometric
information and attribute information of components, some volume statistics and
2D diagram can be generated automatically, which significantly improves the
design and delivery efficiency.
