Abstract

The invention relates to the field of three-dimensional modeling design, and discloses a railway subgrade engineering design method based on a BIM technology, which meets the requirements of three-dimensional rapid modeling and engineering drawing of railway subgrade retaining engineering, realizes rapid three-dimensional display of the railway subgrade engineering, and is convenient to modify andconvey construction key points. The method comprises the following steps: a, reading route information elements, importing the route information elements into three-dimensional modeling software, andgenerating a railway route model; b, associating the route design parameters with a railway route model; c, associating design data of railroad bridges, culverts, tunnels and stations with routes; d,importing roadbed cross section data into the three-dimensional modeling software; e, generating a roadbed model according to the railway line model and the roadbed cross section data; and f, selecting an engineering creation command, inputting corresponding engineering design parameters, and creating a corresponding engineering model on the basis of the roadbed model.

Description

technical field [0001] The invention relates to the field of three-dimensional modeling design, in particular to a BIM technology-based design method for railway embankment engineering. Background technique [0002] Since the goal of BIM technology is information sharing and interoperability, how to establish and use information models is the key to the success of BIM technology application. Before using the information model, the information model must be established, and whether it can meet the application needs is the basis for establishing the information model. [0003] The current mainstream modeling software in the market is all drawn on two-dimensional software, which cannot meet the needs of three-dimensional design and modeling of railway embankment. For different information models, the methods of building the models are very different, the professional attributes are different, the drawing efficiency is low, the three-dimensional display is poor, and the design ...
