Title:	Zhengzhou Yellow River road-cum-railway bridge, China
Abstract:	Zhengzhou Yellow River road-cum-railway bridge accommodates both the Beijing-Guangzhou passenger railway line and the Zhengzhou-Xinxiang inter-city highway, which cross the Yellow River at Zhengzhou, China (Fig. 1). The bridge is 9177 m long and has two distinct sections[1]: the first is a six-pylon continuous steel-concrete composite truss extradosed bridge with a span arrangement of 120 5 ¥168 120 m; the second is a continuous steel-concrete composite truss with a span arrangement of 5 ¥120 m. The main bridge has a double deck, with a six-lane carriageway on the upper deck and a twin-track railway on the lower deck. An inclined truss structure is used for the main bridge superstructure. The upper deck is of concrete, the lower deck uses orthotropic steel solution. The analysis revealed that the main bridge has good rigidity and favourable service conditions for high-speed trains. The main steel truss was constructed by incremental launching.
