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

[0065] The process of the fully automatic modeling method for bridge BIM three-dimensional design in this embodiment mainly includes three processes of generating bridge deck structure, generating bridge pier structure and merging. The three processes are described below.

[0066] (1) Generate bridge deck structure

[0067] The process of generating the bridge deck structure can be further divided into the following steps:

[0068] Step 1. divide the centerline of the bridge deck into several equal sections according to the survey and design data (the size of each equal section is determined by the accuracy requirement of three-dimensional modeling, in the present embodiment, the length of the equal section is one foot, That is, take an equal point every 304.8 mm), read the spatial three-dimensional coordinates of all equal points on the centerline of the bridge deck, and write them into the chart processing software.

[0069] Wherein, the graph processing software of the pr...

Abstract

The invention discloses a bridge three-dimensional design method based on BIM technology. Spatial coordinates generate the bridge deck section shape at the centerline of the bridge deck and the equal point, and determine the shape of the bridge pier control cross section according to the position of the center point of the bridge pier control cross section; according to the bridge deck centerline and the bridge deck section shape at the equal point The bridge deck structure is generated, and the pier structure is generated according to the center point of the pier control cross-section and the shape of the pier control cross-section; the generated bridge deck structure and pier structure are combined to obtain a complete 3D model of the bridge. The invention solves the problem that the existing technology cannot establish corresponding BIM models for bridges with special-shaped and curved structures, has a wide range of applications, improves design efficiency, provides basic model support for bridge construction and operation and maintenance management, and can be widely used in the field of bridge aided design.

Description

technical field [0001] The invention relates to the field of bridge aided design, in particular to a three-dimensional bridge design method based on BIM technology. Background technique [0002] Based on three-dimensional information technology, BIM (Building Information Model) integrates engineering data models of various related information of engineering projects, and its project model information can be stored, Pass and share. The intuition, collaboration, virtualization of BIM model and the flow of data information throughout the engineering process 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 application of BIM technology is still relatively lagging behind. [0003] As an important part of infrastructure, the ...
