Abstract

The invention discloses a modeling and designing method for an elevated structure BIM (Building Information Modeling) model. The method comprises the following steps: S1, generating a spatial three-dimensional line based on an extracted line plane and longitudinal section data; S2, extracting the position of a center point of a pier plane and a corresponding lower structure type, generating an initial model of members of the corresponding pier lower structure, and further generating a three-dimensional model of the lower structure; S3, extracting upper standard structure profile parameters corresponding to line mileage points, generating final upper structure profiles of the line mileage points, and sweeping and lofting based on the spatial three-dimensional line to generate an upper structure three-dimensional model; S4, generating a complete BIM model with an elevated structure. By adopting the method, three-dimensional visualization of an elevated structural design is realized, and the generated model is vivid and easy to modify. Moreover, a whole life period database of the elevated structure is established, so that more bases can be laid for later-stage operation and maintenance.

Description

technical field [0001] The invention belongs to the technical field of elevated design, in particular to an elevated structure BIM model modeling design method. Background technique [0002] In the domestic highway, light rail, municipal and other basic transportation construction, the current design methods for the elevated structure are: (1) use the elevated structure line plane, combine the terrain, planning road network and other controlling factors to arrange the lower structure, and generate the elevated structure design plan ; (2) Use the vertical section of the elevated structure line, combine the plane design, structure size and other information to arrange the upper and lower structures of the bridge, and generate the elevated structure design elevation. [0003] It is obvious that the design method of the above-mentioned elevated structure still stays in the two-dimensional design stage, which has the following disadvantages and limitations: (1) the design result ...
