Abstract

Provided is a modeling and designing method for an elevated structure BIM model, comprising the following steps: S1. Generate a line of a three-dimensional space on the basis of extracted line plane and longitudinal section data; S2. Extract a position of a center point of a pier plane and a corresponding lower structure type, generate an initial model of each component corresponding to the pier lower structure, and then generate a three-dimensional model of the lower structure; S3. Extract an upper standard structure profile parameter corresponding to each line mileage point, generate a final upper structure profile for each line mileage point, and generate a three-dimensional model of the upper structure by sweeping / lofting the three-dimensional space line; and S4. Generate a complete BIM model of an elevated structure. The invention realizes a three-dimensional visualization of an elevated structure design, the generated model image is intuitive, and it is easy to modify the model. Furthermore, the method establishes a full life-cycle database for the elevated structure, providing a basis for subsequent operations and maintenance.

Description

technical field [0001] The invention belongs to the technical field of elevated design, and in particular relates to a BIM model modeling design method for an elevated structure. Background technique [0002] In domestic highway, light rail, municipal and other basic transportation construction, the commonly used design methods for the elevated structure are: (1) Using the elevated structure line plane, combining the terrain, planning road network and other control factors to arrange the substructure to generate the elevated structure design plan ; (2) Using the longitudinal section of the elevated structure line, and combining the information of plane design and construction size, the upper and lower structures of the bridge are arranged to generate the elevation design of the elevated structure. [0003] It is obvious that the above-mentioned design method of the elevated structure is still in the two-dimensional design stage, which has the following shortcomings and limit...
