Abstract
Suspension bridges occupy a core position in the field of long-span bridges owing to their superior spanning capability, rational load-bearing mechanism, and aesthetic appeal, and have exhibited a continuous trend toward increasing span lengths and diversified structural forms. This paper systematically reviews the research progress from three dimensions: structural system evolution, main cable shape-finding theory, and construction control technology. Regarding structural systems, the mechanical characteristics and representative engineering applications of novel systems such as multi-tower multi-cable, spatial cable, and self-anchored suspension bridges are introduced. Regarding shape-finding theory, the applicable conditions and accuracy characteristics of the parabolic method, segmental catenary method (SCM), unstressed length finite element method (including the TCUD method), and intelligent optimization algorithms are discussed. Regarding construction control, the technical characteristics of the AS and PPWS methods are compared, and the major research findings on reference strand chord length adjustment, temperature effects, and cable saddle correction are reviewed. Finally, existing research deficiencies and future directions are identified.
Key words： Suspension bridge; Structural system; Main cable shape-finding; Segmental catenary method; Construction control
