Bridge simulation detection method and system during experiment teaching process

Abstract

The bridge simulation detection method and system used for experimental teaching provided by the present invention, the method includes: establishing a bridge model, and arranging a data acquisition module for collecting bridge state data on the bridge model, preparing a load test loading scheme, and making the bridge according to the loading scheme Under different load conditions, collect the bridge state data of the bridge under different load conditions, process the bridge state data, and obtain bridge detection results; the bridge simulation detection method and system for experimental teaching in the present invention can be used The designed bridge model can conveniently assemble various bridges. The invention has the advantages of simple structure and low cost, is suitable for large-scale teaching and popularization, and can be well used for teaching of bridge static and dynamic load tests and health monitoring.

Description

technical field [0001] The invention relates to the field of bridges and communications, in particular to a bridge simulation detection method and system for experimental teaching. Background technique [0002] With the development of our country's public bridge industry, there are more and more bridges, and many existing bridges have gradually entered the maintenance and repair stage. And with the passage of time, its number is still increasing, and bridge managers have paid more and more attention to the maintenance of bridges. After the completion acceptance and operational use of bridges for a period of time, their bearing capacity and technical status are tested through static and dynamic load tests. Large bridges also need to be kept informed of their usage status and safety through online health monitoring during operation and use. In recent years, my country has invested heavily in infrastructure such as highway projects, which have generally entered the maintenance...

Problems solved by technology

[0003] At present, in the teaching process of bridge testing in colleges and universities, theoretical teaching cannot replace the role of practical teaching

There is no good experimental teaching method for the above-mentioned related content, and it is difficult for students to systematically and comprehensively recognize, understand and master the bridge engineering entity and experimental inspection work, and the teaching effect is generally poor

The main reasons are: the static and dynamic load tests and health monitoring of real bridges require actual engineering projects as support, which requires huge investment in manpower and material resources, the test period is long, and generally the test cannot be repeated. Even if students are allowed to visit the site for practice, in addition to safety risks, students can only see partial test work, and cannot participate in and understand a large number of structural calculations, data analysis, safety assessments, etc.

Because the models used in traditional geotechnical engineering practice teaching are generally concrete components, steel components, etc., which are difficult to assemble and build by themselves, and generally focus on verification tests. Compared with other majors, it is difficult for students to complete independent and innovative tests independently. The learning interest and enthusiasm are not high, and the teaching effect is not good

Therefore, there is an urgent need for a new technical means that can solve the problems existing in the teaching of bridge inspection that the field test needs to be based on the actual bridge, the field organization and management are difficult, the cost is high, and the risk is high.
