Research purposes: Yibin Lingang Yangtze River Bridge is located near Keshuiba in Lingang District of the Yibin City. It is a shared crossing of the newly-built Chuannan intercity railway, Chongqing-Kunming high-speed railway and Yibin municipal road planning. In order to save channel resources, reduce demolition and land use, the bridge adopts a cable-stayed bridge with road and railway traffic one level. This paper studies the bridge location, beam type, design and construction of the Yibin Lingang Yangtze River Bridge.
Research conclusions: (1) The bridge location and span of the river-crossing bridge are comprehensively determined under the influence of river course, navigation, flood flow, fish protection and other factors. (2) On the premise of meeting the functional requirements and technical standards, the structural form of the bridge should be comprehensively compared and selected from the aspects of technology, economic index, construction, landscape, approach dredging, etc. (3) The design should focus on the relative position between railways, between railways and roads, and the interaction between road and railway traffic. (4) The construction scheme should be comprehensively determined in combination with the terrain, transportation conditions and bridge type. (5) The research results can be applied to the design of railway long-span cable-stayed bridge and road-railway on one level bridge.
