Construction Technology of Long-span Suspension Bridge Structure with Flexural-torsional Steel Box Arch and Tie Rod
The main structure of the Huacai Haikou Bay Plaza project consists of tower A and tower B,as well as podium C and podium D.The podium C is equipped with a large-span suspension bridge structure with flexural-torsional steel box arches and tie rods,which is connected to tower A and tower B.The suspension bridge structure has the characteristics of novel shape,mostly curved main components,complex form,with variable component cross-sections and high construction difficulty.Based on the structural form,characteristics and actual site conditions of the suspension bridge,the key and difficult points of construction are analyzed,and the key construction technologies of steel grating,arch foot nodes,inner arches,horizontal tie rods and outer arches,diagonal tie rods and the curved suspension bridge are studied.By combining construction simulation with process control,the quality and safety of the project are guaranteed,the construction period is shortened,and the cost is saved.
