(接上期)主缆及索夹安装主缆是悬索桥的主要承重构件,其防腐及抗疲劳等性能直接决定桥梁的使用寿命。现代悬索桥主缆一般采用强度高、弹性模量高、空隙率低、防锈蚀能力强的镀锌高强度平行钢丝索。主缆的施工方法一般采用预制平行索股法(PPWS法)和空中纺丝法(AS法)。预制平行索股法是
(Continued) The main cable and cable clip installation The main cable is the main load-bearing components of the suspension bridge, and its anti-corrosion and anti-fatigue properties directly determine the service life of the bridge. Modern suspension bridge main cable generally adopts the high strength, high modulus of elasticity, low voidage, anti-corrosion ability of galvanized high-strength parallel steel wire rope. The main cable construction methods generally use precast parallel stock method (PPWS method) and air spinning method (AS method). Prefabricated parallel stock method is
