CFST arch bridges can save material because the steel and concrete of the cross section can play a full role due to the small eccentricity of the arch ring. However, the installation cost is high (about 20% of the total price). Suspension lifting and cable-stayed fastening-hanging system are the main methods for construction of arch bridges without scaffold system. Note that the suspension lifting system requires suspension towers, while the buckle system requires buckle tower. The suspension tower and buckle tower account for about 50% of the cost of the suspension lifting and cable-stayed fastening-hanging systems.

摘要

CFST arch bridges can save material because the steel and concrete of the cross section can play a full role due to the small eccentricity of the arch ring. However, the installation cost is high (about 20% of the total price). Suspension lifting and cable-stayed fastening-hanging system are the main methods for construction of arch bridges without scaffold system. Note that the suspension lifting system requires suspension towers, while the buckle system requires buckle tower. The suspension tower and buckle tower account for about 50% of the cost of the suspension lifting and cable-stayed fastening-hanging systems.
