Problems solved by technology
The cost-benefit ratio of the construction simulation method is too low, that is, the time and cost of the test are too high, which affects the schedule of the project and the economic benefits of the project
[0004] Building Information Modeling (BIM) is a new type of information technology applied in the field of engineering construction. It can integrate all geometric model information, functional requirements and component performance, and realize information sharing and transmission throughout the project life cycle; currently There is no application of introducing BIM technology into steel bridge deck pavement engineering in existing technologies

Embodiment Construction
[0022] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings.
[0023] A BIM technology-based steel bridge deck pavement construction simulation simulation method of the present invention, as the name suggests, is to use BIM technology for steel bridge deck pavement construction simulation, and its theoretical basis is as follows figure 1 , figure 1 A technical framework for the simulation of steel bridge deck pavement construction using the BIM simulation platform is given. The technical framework includes the following five layers:
[0024] 1. The data layer, which is the data "warehouse". Its main body is structured data information, that is, BIM database, which contains IFC standard format information, and can store unstructured data information, that is, non-IFC standard format information and project progress information, etc. Process information data.
[0025] 2. The data interface layer is the c...

The invention discloses a BIM technology-based steel bridge deck pavement construction simulation method, including the following steps: Step: 1) Data collection, including geographic information of the construction site, three-dimensional dimensions of the steel bridge and its deck, and the steel bridge 2) Establish construction sub-models based on the BIM platform, including construction site sub-model, steel bridge sub-model, steel bridge deck pavement layer sub-model and construction machinery sub-model; The construction process information is obtained from the construction plan of the installation project, and the construction sub-model data and construction process information are imported into the construction simulation platform to assemble the construction model; 4) Based on the construction model, the steel bridge deck pavement construction simulation animation is produced. This method uses the BIM platform to add the time dimension on the basis of 3D visualization modeling. By inputting the construction plan in the construction simulation platform, the feasibility of the construction plan can be verified intuitively and quickly, which helps to improve the efficiency of pavement construction. Reduce the error rate.
Description
technical field [0001] The invention relates to a construction simulation simulation method based on BIM technology, in particular to a construction simulation simulation method of a steel bridge deck pavement engineering, and belongs to the technical field of steel bridge deck pavement engineering. Background technique [0002] my country's long-span steel structure bridges are paved with steel deck asphalt. At present, the most widely used and effective pavement material for steel deck pavement is epoxy asphalt concrete (EA). It has high strength, strong resistance to plastic flow and permanent deformation at high temperature, good crack resistance at low temperature, and excellent fatigue resistance. However, the performance of epoxy asphalt concrete is greatly affected by changes in temperature, time and other factors during molding, and there are strict requirements on the weather, temperature and air humidity on the day of construction, and a long enough curing period ...
