Abstract
Hutong Changjiang River Bridge, a key project of the newly-built Shanghai-Nantong railway and Nantong-Suzhou-Jiaxing inter-city railway, will be the longest span high way-railway bridge in the world and 3 bridge sites of Shier-wei, Shisanwei and Xijiegang in Chengtong reach of Changjiang River were primarily selected and compared from aspects of river-bed evolution,including the variation of shoreline, contour line, talweg and cross-sections. The results show that the selected river reach is qualified to bridge construction in general, the Shierwei cross-section is the most stable while Xijiegang cross-section is poorest in stability;taking account of the shoreline resources utilization, Shisanwei cross-section is recommended as the bridge site. Relevant study results provide technical basis to the design and decision making of Hutong Yangtze River Bridge.关键词
