Construction Method Of Cable-Stayed-Truss Bridge

Cable-stayed-truss bridge is a new bridge, which has the characteristics of continuous rigid frame bridge and light force of truss, so it applies to both the large-span, also applies to small and medium-span .And it applies to the narrow bridge, also applies to the high-grade highway bridge. She has a certain vitality and unique advantages.Cable-stayed-truss bridge's is the system that the small rigidity bars integrated combination of larger structural rigidity bars and prestressed concrete rigid drawbars replace flexible cable-stayed cables.Cable-stayed-truss bridge has following several forms: a cable-stayed truss rigid frame bridge with hole or hinge in its mid-span; continuous cable-stayed truss bridge; cable-stayed truss T rigid frame bridge with hinge or hole in its mid-span; continuous cable-stayed truss rigid frame bridge.This paper presents a general construction method of cable-stayed -truss bridge, while relying on Kazi Bay Bridge of Zigui County in the three Gorges reservoir area. Through specific analysis and research of cable-stayed-truss bridge's construction programme ,we could provide following similar to the bridge with the possible reference.
