Hong-shui river especially big bridge is a kind of semi hybrid steel-concrete comoposite cable-stayed bridge. The erection of Guizhou side span adopt the incremental launching construction method, which was composite beam; The erection of midspan adopt cable-stayed buckled method, which was composite beam; The erection of Guangxi side span adopt support frame casting in situ construction method, which was concrete π type girder. The paper focus on the characteristics of the asymmetrical structure forma and asymmetric construction method of Hong-shui river especially big bridge, discussing the key contents of construction monitoring, which can offer reference and consulting for related engineering.
