[0003] On the one hand, temperature fluctuations will cause the steel box arch ribs to expand and contract, thus changing the linear shape of the arch ribs. If not effectively controlled, it may affect the stability and safety of the structure, as well as its fit with other structural parts.

[0004] On the other hand, the thermal stress caused by temperature changes may change the stress distribution inside the steel box arch rib, which may have an adverse effect on the durability of the structure in the long term;

[0005] Traditional control methods have problems such as insufficient precision, weak adaptability, and failure to fully consider the complex influence of temperature. They cannot meet the needs of high-precision linear shape and stress control of steel box arch ribs under different temperature conditions.

Secondly, the real-time monitoring temperature data sequence of the area where the steel box arch rib to be built is located is acquired through a sensor cycle, and the acquired real-time monitoring temperature data sequence is analyzed, so as to realize accurate and effective analysis of representative monitoring temperature data at different times. The effective determination provides reliable data support for the state characteristic analysis of the linear shape and stress of the steel box arch rib. Finally, the representative monitoring temperature data is parsed through the target analysis model to effectively determine the state characteristics of the linear shape and stress of the steel box arch rib to be built at different times, so as to lock the optimal closing temperature of the steel box arch rib according to the obtained linear shape and stress state characteristics, further realize the effective control of the linear shape and stress of the steel box arch rib, ensure that the linear shape and stress can reach the optimal state, improve the performance and quality of the steel box arch rib, and provide effective decision-making support for the construction of the steel box arch rib.
