1 Overview The steel structure is widely used in railway station projects due to its environmentally friendly, fast and recyclable features. The steel structure of the track layer of the Jinan West Railway Station Station of the Beijing-Shanghai high-speed railway is designed with the large-section column beam members (H-shaped steel beam height 3 350 mm), the material is Q345GJC, the carbon equivalent is high, and the field welding Concentration of seams, quality control is difficult, especially the direct impact of low temperature welding on the quality of welding in winter, is related to the smooth implementation of the entire project. 2 welding engineering difficulties 2. 1 Large amount of welding Jinan West Railway Station is one of the five starting and ending stations of the Beijing-Shanghai high-speed railway. It is a large-scale comprehensive transportation hub project with a steel capacity of 21,000 tons. The construction of the track layer is 202 m long and 107 m wide. The steel structure has a capacity of 13,000 tons and the steel consumption per square meter is 600 kg. The design has 128 steel columns and 326 steel beams, which are connected by full penetration welding. A total of 652 welds, the total length of the weld on site is 2 000 m, and the thickness of the welded steel plate is 35 to 70 mm. The planned welding duration is 40 days. Conclusion Since the operation of the Beijing-Shanghai high-speed railway, the station has played an important role. The on-site lighting effect is very good and has been recognized by the railway bureaus and passengers. The Beijing South Railway Station and the Tianjin West Railway Station are playing their respective roles. Thanks to the intelligent lighting control system, the staff can flexibly control according to actual needs and achieve good results in saving energy.
