First, after conducting research on the comparison and selection of the construction scheme, lifting process, quality control and other aspects, a floor assembly + hydraulic lifting + overhead supplementary bar construction plan was proposed. The large-section steel beam and truss hybrid structure system with different bottom chord elevations was divided into two units for synchronous lifting, with weights of 715 tons and 340 tons, lifting heights of 21.5 metres and 15 metres, and a maximum span of 50.4 metres , Second, the maximum vertical displacement, maximum stress ratio of the members, lifting reaction force frame and overall stability of the hybrid structure during the lifting process were analysed, and the results showed that they all met the requirements. Finally, the monitoring data of the field construction process were in good agreement with the numerical calculation results, further verifying the rationality and feasibility of hydraulic synchronous lifting technology, which can provide guidance and a reference for the construction of similar long-span hybrid steel structures.
