Key Technology for Overall Incremental Launching of Steel Structure of the Super-Iarge Elevated Station Building Overpassing the Operational Line at Lushan Railway Station
To address the challenges in constructing the special-shaped unequal-height steel structure system composed of an over-bridge,a corridor,and an elevated station building,overpassing the operational railway line,a numerical analysis model was developed.This model was used to conduct a simulation analysis on the entire incremental launching process.Through wind tunnel tests on critical parts of the structure,taking into account factors like extreme temperature differences,high winds,and the combined effects of these conditions,the load bearing and deformation characteristics of the special-shaped unequal-height structural system overpassing the operational railway line during the construction are analyzed.The proposed construction approach can satisfy the safety requirements for the special-shaped unequal-height steel structure system overpassing the operational railway line.A monitoring and early warning system for construction risks of the special-shaped unequal-height steel structure system overpassing the operational line was established to implement quantitative assessment and intelligent early warning of construction risks of the structural system overpassing the operational line.
