1BIM technology overview
1. 1 BIM concept
BIM technology is called BuildingInformationModeling, which is a kind of building model design based on all relevant information of building projects. The essence of this model is to use digital information to simulate the process of building construction and the related definite information. The unique advantage of this architectural model is that it has eight characteristics: information integrity, information correlation, information consistency, visualization, adjustment, simulation, optimization and drawing. Simply put, BIM technology is a comprehensive technology integrating geometric relationship, spatial relationship and architectural knowledge.
BIM technology can show various details of architecture with visual digital information, including building life cycle, building process, building materials, building budget and so on. From a more specific point of view, BIM technology mainly includes three dimensions in design, namely resources, behavior and payment. Obtaining these three aspects of information can, to a great extent, provide specific methods for the implementation of various projects in enterprises and design practical contents of construction. Because BIM technology itself is the application of digital information, it can be used in the fields of design, management and construction to establish corresponding models, which can obviously improve the efficiency of the whole project design, construction, construction, operation and management. In addition, it can also control various hidden dangers in the construction and operation of construction projects to a great extent.
1.2 overview of bridge engineering
Bridge engineering is a kind of architectural engineering, including structural design, construction, construction, operation, management and maintenance of bridges. After the bridge project was put into operation, it began to perform the function of serving the society. In the process of social service, we often encounter various unsafe factors that hinder the performance of bridge duties, such as natural factors that affect traffic, and of course some unnatural factors. All these will lead to social and economic losses.
Therefore, for bridge engineering, every process of structural design, construction, construction, operation, management and maintenance of bridge building is very important, and every process will have a certain impact on the function of bridge serving the society. With the continuous development of economy, there are more and more bridge projects in China, and a large number of bridges are put into use every year. Faced with a large number of bridges that need to be operated, it is imperative to design effective management schemes. With the continuous development of science and technology, various advanced technologies have been put into the operation of bridge engineering, providing a good platform for the efficient and safe operation of bridges.
2. Problems existing in the current bridge engineering operation stage
2. 1 Safety issues before the operation stage of bridge engineering
The operation of bridge engineering depends on the structural design and construction quality of the bridge ahead. In recent years, this situation often occurs in the construction of some bridge projects in China. Due to the imperfect construction scheme, there are various safety hazards, which eventually lead to major safety accidents, affect the operation effect of bridge engineering, and even seriously affect the development of China's transportation industry, bringing inevitable losses to social and economic benefits. In addition to the defects in design and construction scheme, there is still a big difficulty in the construction process of bridge engineering quality, that is, the problem of overall consideration. In the process of bridge engineering construction, in order to ensure the overall quality of bridge engineering and speed up the construction efficiency, it is particularly important to make overall consideration. In the current process of bridge construction, the grasp of overall consideration needs to be improved.
2.2 At present, the safety assessment system of bridge operation stage is not perfect.
In the process of bridge engineering operation, besides managing and classifying all kinds of information, it is also very important to evaluate the safety of the bridge, which is related to whether the bridge needs maintenance or not and directly affects the safety of the whole bridge engineering. In the current bridge engineering operation, the evaluation of bridge safety performance needs to be strengthened, and the traditional safety performance evaluation system can not achieve bridge safety supervision very accurately and quickly, so it does not have a very sensitive evaluation in finding safety hazards.
2.3 At present, the personnel management efficiency in the operation stage of bridge engineering is low.
At present, the management system of bridge engineering operation stage is largely based on manual operation, which is often not enough for the growing bridge engineering. That is to say, in the face of the mushrooming bridge projects, human resources can't cope with all kinds of problems that may occur in the operation process and the collection, management and evaluation of massive information, which will make the management efficiency of bridge projects in the operation stage low. This will affect the social and economic benefits that bridge engineering can bring. On the other hand, the inefficiency of manual management may also lead to untimely information processing. If the safety problems related to bridge operation are not found and dealt with in time, it is likely to cause more serious losses. Therefore, the problem of low personnel management efficiency in the current bridge engineering operation stage needs to be solved urgently.
2.4 The current bridge engineering operation information management system is not perfect.
At present, the information management system of bridge engineering operation is not perfect, that is to say, there is not a perfect and reliable information management system to sort out the relevant information and data of bridge engineering operation process. There are often a lot of bridge engineering operation information, and the classification, collation, storage, extraction and update of these massive information often require high information management systems. At present, the traditional information management model has been unable to adapt to the management of massive information, resulting in the lack of information management in bridge operation.
Application of 3BIM technology in bridge engineering operation stage
3. 1 supervise the early operation of bridge engineering with BIM technology.
In the process of bridge construction, the most important problem is to monitor the safety of the whole construction process. Using BIM technology, the overall safety supervision of the whole construction project can be realized to a great extent. From the specific operation point of view, through the application of BIM technology in the construction process of building engineering quality, the safety supervision system for the whole construction process is established, and then the problems existing in the design and construction process are effectively summarized from digital information by using digital effects, so that these problems can be solved efficiently, thus greatly improving the quality of building engineering and ensuring the personal safety of construction technicians.
In the process of safety supervision system construction, the most important thing is to establish a perfect BIM safety supervision system according to the characteristics of various bridge projects. Because of the important role of the whole safety supervision system, the design of the supervision system has become very complicated, so the establishment of the system can not be completed in a short time. Therefore, before the establishment of the safety supervision system, it is often necessary to make an in-depth investigation of the environment of the whole bridge engineering building, and on this basis, make a complete and accurate prediction and estimation of the whole bridge construction process. Only through actual investigation and a certain degree of in-depth understanding of the whole process of bridge construction can the effectiveness of BIM safety supervision system be guaranteed.
3.2 the use of BIM technology to establish a bridge safety assessment system
With the rapid development of social economy, science and technology, the number of construction projects has surged, especially the number of bridge projects has increased day by day, and various sea-crossing, river-crossing and river-crossing projects have emerged one after another. The operation of bridge engineering plays a decisive role in the service life of bridge engineering, so it is very important to have a series of complete and effective operation schemes. Through the application of BIM technology in the operation process of bridge engineering, a safety evaluation system is established for the whole operation process, and then the problems existing in the operation process are effectively summarized from digital information by using digital effects, and the maintenance needs are evaluated, so as to effectively solve these problems and greatly improve the safety factor of bridge engineering in the operation stage, which not only contributes to the improvement of social and economic benefits, but also reduces the potential safety hazards in the use of bridges. Using BIM technology to establish a bridge operation safety evaluation system. Compared with the traditional evaluation system, BIM technology can provide a more accurate and rapid evaluation report, that is to say, BIM technology has timeliness in providing information on bridge safety, ensuring the sensitivity to potential safety hazards during bridge operation, thus reducing the possibility of safety accidents caused by unnatural factors.
3.3 Using BIM technology to improve the whole process management level of bridge engineering operation
BIM technology is based on transforming all kinds of real information into digital information and using its own virtual database. This technology can play an important role in the operation and management of bridge engineering. From the point of view of managers, when all aspects of bridge engineering quality information are presented in a digital way and can be analyzed by computer technology, the work intensity of managers is greatly slowed down to some extent. In addition, in the process of bridge engineering operation, using BIM technology to monitor the whole process of bridge engineering is helpful to find problems in time and solve them effectively in time.
3.4BIM technology in the application of bridge engineering operation information management
Because there is a large amount of information in the operation of bridge engineering, the classification, sorting, storage, extraction and updating of these massive information often require a high-level information management system. At present, the traditional information management model has been unable to adapt to the management of massive information, resulting in the lack of relevant information sorting in the operation of bridge. Therefore, BIM technology is introduced into the information management of bridge engineering operation, and the visual digital information of BIM technology itself is used for simulation processing, so that the information is complete, relevant, unified and visualized, and then the data information is adjusted, simulated and optimized, and finally the massive information is displayed in the form of graphics to realize the visualization of information, thus solving the problem of improper information processing in the traditional information management system.
Specifically, for the operation and management of bridge engineering, we can improve the traditional information management system under the condition of BIM technology, develop a bridge engineering operation information management system suitable for the era of big data, and train the managers in the operation stage of bridge engineering to familiarize them with the operation of the new system in BIM environment, and complete the supervision and operation of the system according to different process instructions, so as to collect, classify, store, extract, manage and visually output the information, and improve the information. The bridge engineering operation information management system based on BIM technology can not only collect, classify, store, extract, manage and visually output information, but also upload, modify and delete information as needed. In order to further ensure the update and replacement of bridge engineering operation information, so as to improve the efficiency of information management and provide more timely and meaningful information for bridge engineering operation management personnel.
