Bridge structure crack health monitoring analysis method

Abstract

The invention discloses a bridge structure crack health monitoring analysis method. The bridge structure crack health monitoring analysis method comprises the following steps: according to a bridge structure cracking condition, a plurality of crack sensors are arranged on the cracks of the key stress parts of a selected structure; framework acquisition and transmission equipment remotely monitor and acquire the original monitoring crack numerical value acquired by the transmission equipment; the data processing is carried out on the received original monitoring crack numerical value; the threshold value alarm on the total width and the month speed is given according to the processed original monitoring crack numerical value. According to the method, cracks are evaluated and analyzed through the development tendency and the development rate of cracks, and then the threshold value early warning is carried out when the crack development rate and the absolute width exceed a certain limit value. As a result, the cracks of the bridge structure can be effectively monitored in real time, so that the unattended alarm function is realized. After the system judges that the monitoring value exceeds a threshold value, the alarm information is pushed to the engineering personnel. Therefore, the engineering personnel can arrive at the site for treatment at the first time, and the use safety of the bridge is guaranteed.

Description

technical field [0001] The invention relates to the technical field of crack detection, in particular to a health monitoring and analysis method for cracks in bridge structures. Background technique [0002] With the rapid development of my country's national economic construction, more and more large-scale infrastructure construction plays an extremely important role, especially large-scale bridges. Due to the long-term bearing of complex vehicle loads on bridges, structural cracks often appear, resulting in attenuation of the resistance of the bridge structure, which may lead to catastrophic accidents in extreme cases. [0003] The unstressed cracks of bridge structures are related to the durability of bridge structures, and the stressed cracks are related to the health and safety of bridge structures. Therefore, the bridge management department will invest a lot of manpower, material resources and financial resources to carry out manual inspection of bridge cracks every ...
