摘要
武汉天兴洲公铁两用长江大桥主桥为(98+196+504+196+98)m双塔三索面钢桁斜拉桥,主梁为3片主桁的板桁结合钢桁梁,上层为6车道公路,下层为双线客运专线、双线Ⅰ级铁路。其中铁路桥面采用纵横梁体系的混凝土板结合道碴桥面。介绍铁路混凝土板结合桥面系模型试验的结构设计及试验方法。
The main bridge of Wuhan Tianxingzhou Changjiang River Rail-cum-Road Bridge is a double pylon and triple cable plane steel truss cable-stayed bridge with span arrangement （98 ＋196＋504＋196＋98） m. The main girder of the bridge is a composite girder made up of three main steel trusses and concrete slabs. On the upper deck of the bridge, six-lane roadway is arranged while on the lower deck, the double-track passenger dedicated railway, the Grade Ⅰ doub- le-track railway, is set. Of the overall main bridge, the railway deck is designed as a concrete slab composite ballast deck formed by longitudinal and transverse girder system. In this paper, the structural design and testing methods for the test models of the concrete slab composite railway floor system are presented.
