Check method for BIM design model of railroad bridge

Abstract

The invention discloses a check method for a BIM design model of a railroad bridge. The method comprises the steps that completeness check, normativity check and accuracy check are performed on the BIM model, wherein according to the completeness check, a structure tree and property information in the BIM model are checked according to a bridge two-dimensional design drawing, and sampling is performed for material list check to ensure that parameter information in the making process of the BIM model is input completely; according to the normativity check, a spot check mode is adopted to select typical beam-type key segments for three-dimensional model visual check to ensure that the BIM model conforms to a modeling standard; according to the accuracy check, collision check of a full check mode and two-dimensional drawing output check of the spot check mode are adopted to perform collision check on the model to ensure the accuracy of spatial relation information of the BIM model; and whether the BIM model has completeness and / or accuracy and / or normativity problems is judged. The method has the advantages that the technical method and the standard process for check of the BIM design model of the railroad bridge are constructed, and the completeness of borne design information, the accuracy of a spatial relation and the normativity of a creation mode of the BIM model are ensured.

Description

technical field [0001] The invention relates to the technical field of bridge construction, in particular to a method for checking a BIM design model of a railway bridge. Background technique [0002] BIM (Building information Modeling) is a collection of a series of tools, processes and methods for the realization of engineering digitalization, design and construction visualization and operation intelligence. It is a deep integration of civil engineering science and IT technology. With the maturity and development of BIM technology, its application value is highlighted, and the application of BIM in railway bridges is becoming more and more popular. Since the BIM model is the basis for BIM-based full life cycle management, the quality of the model is directly related to the accuracy, consistency and collaboration of information in the application of BIM technology. Therefore, effective control of modeling quality is the focus of BIM technology application. [0003] At pre...

Problems solved by technology

At present, there are few personnel who have strong professional knowledge and are familiar with BIM software. In addition, different personnel have different modeling ideas. As a result, the efficiency of BIM modeling is not high, and the built model cannot avoid problems, which affects the modeling work. the quality of

[0004] At present, the model inspection of railway bridges is usually completed by the modelers themselves, lacking mature methods and fixed inspection procedures. Considering the inertial influence of the modelers' existing modeling ideas, it is difficult to find problems in the BIM model, and the bridge cannot be guaranteed. BIM Design Model Quality
