Abstract:Aiming at the design difficulties of 17 meters super thick backfill, super long structure, bearing train dynamic load and complex roof space structure in the station building of Weifang North Station, softwares of YJK, 3D3S and ABAQUS were used to design, calculate and analyze negative friction, temperature effect, train equivalent load and node finite element, and reinforcement measures such as taking into account the adverse effects of negative friction, increasing plate reinforcement, taking the envelope value of the train equivalent load and simplified code load, and processing smooth transition processing on steel structure nodes were taken. The  results show that the design is reasonable and the strengthening measures are effective, which ensure the safety and reliability of the structure. 

Keywords:Weifang North Station;super thick backfill;super long structure;train dynamic load;large-span space steel truss
