BIM (Building Information Modeling) technology based bridge three-dimensional design method

Abstract

The invention discloses a BIM (Building Information Modeling) technology based bridge three-dimensional design method. The method comprises the steps of: extracting three-dimensional space coordinates of an equal division point of a central line of a bridge surface and determining the position of a central point of the control cross section of a bridge pier; generating a bridge surface section shape at the equal division point and the central line of the bridge surface according to the three-dimensional space coordinates of the equal division point of the central line of the bridge surface, and determining a control cross section shape of the bridge pier according to the position of the central point of the control cross section of the bridge pier; generating a bridge surface structure according to the bridge surface section shape at the equal division point and the central line of the bridge surface, and generating a bridge pier structure according to the central point of the control cross section of the bridge pier and the control cross section shape of the bridge pier; and combining the generated bridge surface structure and bridge pier structure to obtain a complete bridge three-dimensional model. The method solves the problem in the prior art that corresponding BIM models cannot be established for bridges with deformed and curved structures, is wide in application range, improves the design efficiency, provides basic model support for bridge construction and operation and maintenance management, and can be widely applied to the field of bridge aided design.

Description

technical field [0001] The invention relates to the field of bridge auxiliary design, in particular to a three-dimensional bridge design method based on BIM technology. Background technique [0002] BIM (Building Information Model) is based on three-dimensional information technology and integrates engineering data models of various related information of engineering projects, and its project model information can be stored and stored throughout the entire life cycle from pre-project planning, design, construction to post-operation Pass and share. The intuition, collaboration, virtualization and flow of data and information of BIM model in the whole process of engineering make BIM technology gradually replace traditional two-dimensional modeling technology. In the construction industry at home and abroad, especially in complex single buildings, BIM technology has been applied to a certain extent, but in the field of civil infrastructure such as bridges, railways, etc., the ...

AI Technical Summary

Problems solved by technology

Although REVIT software has many advantages, it is still relatively lacking in the modeling ability of special-shaped and three-dimensional space structures. However, it is difficult to establish a corresponding BIM model, which seriously affects the application of BIM technology in bridge engineering
