According to the suspension bridge steel box girder hoisting method and system, synchronous collection of elevation data and internal force data of multiple hoisting points is achieved by arranging the monitoring module, and full-process intelligent control is formed by combining the steps of filtering fusion, hierarchical decision making and automatic deviation correction. According to the method, the spatial pose change and the stress state of the steel box girder in the hoisting process can be comprehensively captured, and the hoisting precision and safety are improved; by collecting and processing data in real time, the system can quickly respond to external interference (such as wind load or construction load fluctuation), dynamically maintain the balance of a hoisting point and reduce the risk caused by manual intervention lag; the introduction of a preset reference value provides a reliable reference for data comparison, and the judgment accuracy is ensured; and an automatic alarm and adjustment mechanism realizes closed-loop management, ensures the continuous and stable hoisting process, and solves the technical problems of low safety, poor positioning precision and difficulty in meeting the high-standard construction requirement of the large-tonnage steel box girder caused by difficulty in synchronization and coordination of multiple hoisting points in the hoisting process in the prior art.
