Research On The Application Of BIM Technology In Bridge Engineering

In China,thousands of bridges are built every year.Based on the traditional design and construction mode of the engineering field,this requires a lot of bridge design,construction and operation management personnel and their long-term efforts.In the design stage of bridge engineering,designers need to carry out a large number of drawing,reshaping and estimating the amount of work.This process is often easy to cause information loss and transmission faults.In the construction stage,imperfect construction drawings and inexperienced construction workers often lead to chaos and quality and safety problems at the construction site.In the operation and management stage,due to the independent work of the participants,incomplete information and ineffective communication,which is likely to cause the cost of operation and maintenance of the bridge project.The rise and the decline in the quality of operation and maintenance work.Compared with the traditional engineering construction mode,BIM technology designed to serve the whole life cycle of engineering projects can not only shorten the design and construction cycle,reduce the difficulty and cost of the construction process,but also analyze and guide the bridge design and construction process and improve the bridge.Engineering safety and economy.This thesis intends to combine engineering examples,exploring the application innovation of BIM technology in parametric modeling,visual programming(dynamo)and adaptive components,according to the principle of bridge engineering design and BIM technology model classification and model splitting,and establish and accumulate the corresponding bridge type component modules,which are used to realize the assembly design for a specific bridge type in the future,and lay a foundation for rapid and efficient model establishment and engineering calculation through the call and rapid change of the existing module.At the same time,taking the concrete complex components in the suspension bridge as an example,the thesis will expound the block mode of the model,which will be helpful for improving the disadvantages of the traditional two-dimensional design in the bridge engineering design for the complex components,and providing the real-time completecomponents for the bridge engineering design and construction process.This is used as a reference for other bridge projects.Finally,taking bridge engineering project as an example,numerical simulation,engineering quantity statistics,3D solid steel design and other applications are carried out to discuss the application of BIM technology bridge design and construction.
