BIM (Building Information Modeling)-based three-dimensional modeling method and system for subway station enclosure structure and medium

Abstract

The invention discloses a BIM (Building Information Modeling)-based three-dimensional modeling method and a system for a subway station enclosure structure and a medium, and belongs to the technical field of subway station enclosure structure modeling. Based on the problems that construction of an existing metro enclosure structure needs to depend on CAD. Meanwhile, model construction is complex, and construction efficiency is low, a Revit software secondary development technology is utilized, a subway station enclosure structure rapid modeling plug-in and a subway station enclosure parameter input interface are constructed, modeling does not depend on CAD any more, and the construction efficiency is high. The building of the subway station enclosure structure BIM model is achieved by manually setting parameters and calling families, the method is suitable for building the subway station enclosure structure BIM model, the BIM modeling efficiency is improved, the BIM modeling difficulty is reduced, and the BIM application requirement is met.

Description

technical field [0001] The invention belongs to the technical field of modeling of subway station enclosure structures, and more specifically relates to a BIM-based three-dimensional modeling method, system and medium of subway station enclosure structures. Background technique [0002] BIM technology (Building Information Modeling) is a multi-dimensional model information integration technology developed on the basis of computer-aided design. In the past two years, more and more urban rail transit engineering projects have begun to apply BIM technology, but at the present stage, the application of BIM technology is still dominated by construction units, from construction unit modeling to BIM application. In the process of BIM technology application, there are The BIM modeling cycle is long and the modeling quality cannot be guaranteed, which leads to major problems in the application of BIM. [0003] In urban rail transit engineering, the subway station enclosure structure...

Problems solved by technology

However, this method has the same shortcomings as the previous papers, and this method only realizes the rapid layout of the subway station enclosure piles by identifying the CAD layer. The requirements for the CAD layer are relatively high, and it does not cover the underground diaphragm wall, crown beam, The modeling of supports and other structures cannot completely establish the BIM model of the subway station enclosure structure

[0009] Finally, look at the patent application: the establishment method, device and storage medium of the BIM model of the subway station enclosure structure are available. This patent uses the nodes in the existing relatively mature Dynamo to realize the call of the related family of the subway enclosure structure, and realizes rapid construction. The scheme uses Dynamo programming to realize the automatic creation, steps and parameterization of the underground station enclosure structure, and improves the efficiency of BIM modeling through automatic construction. However, the model construction is still relatively complicated, and it is difficult to model the subway station enclosure structure. , less practical
