Embodiment Construction

[0030] The following is based on Figure 1 to Figure 4 The specific embodiment of the present invention is further described:

[0031] see figure 1 , a method for classifying and coding bridge engineering components based on IFD, comprising the following steps:

[0032] Step 1: Based on the requirements in the operation and maintenance phase, divide the bridge engineering components according to the surface classification method, and divide them from the two dimensions of entity component type and location information.

[0033] The step 1 specifically includes: dividing the bridge engineering components into six hierarchical structures based on the requirements of the operation and maintenance phase and according to the surface classification method and from the entity component type and location information, and the six hierarchical structures are respectively Direction, span, substructure, part type, component type and component, the smallest unit is component. Among them...

Abstract

The invention discloses a bridge engineering component classification and coding method based on IFD. The type and position information of solid components are made into bridge engineering component coding table and attribute coding table respectively. The code in the code table of bridge engineering components and the code in the attribute code table are combined by basic operation symbols. The bridge BIM model is established by BIM software, and the code in the bridge engineering component coding table, the code in the attribute coding table and the combination code are assigned to the bridge engineering components of different levels. Fast retrieval of bridge engineering components is realized by coding in bridge engineering component coding table, coding in attribute coding table or combination coding. The invention realizes the information sharing and transmission of the bridge engineering component and the quick retrieval of the bridge engineering component, the unique confirmation of the bridge engineering component, and lays the foundation for the real bridge BIM application.

Description

technical field [0001] The invention relates to the field of BIM application in the bridge operation and maintenance phase, in particular to an IFD-based method for classifying and coding bridge engineering components. Background technique [0002] Building Information Modeling (Building Information Modeling), referred to as BIM, is a digital electronic model that contains all the information of the facility, a virtual substitute for the facility, and a knowledge resource for facility information sharing, providing a reliable basis for decision-making. At present, BIM technology is a popular research field in my country's civil engineering industry, but the imperfection of BIM technical standards in the field of bridge engineering limits the application of BIM in the field of bridge engineering. [0003] At present, there is no uniform standard for the BIM application of bridge engineering, and different BIM systems have been developed for different business parties or diffe...
