沪通长江大桥是新建沪通铁路及通苏嘉城际铁路的控制性工程,建成后将成为世界上跨度最大的公铁两用斜拉桥。初步选定十二圩、十三圩和西界港作为备选桥位,随后通过河床演变分析,从岸线、等高线、深泓线和断面的变化4个方面对桥位进行了深入比选。分析结果认为:工程河段具备建桥的宏观河势条件;十二圩河段较为稳定,十三圩河段次之,西界港河段变化较大。综合考虑岸线资源利用,推荐十三圩桥位方案,研究成果可为拟建桥梁的设计与决策提供更为充分的技术依据。
滬通長江大橋是新建滬通鐵路及通囌嘉城際鐵路的控製性工程,建成後將成為世界上跨度最大的公鐵兩用斜拉橋。初步選定十二圩、十三圩和西界港作為備選橋位,隨後通過河床縯變分析,從岸線、等高線、深泓線和斷麵的變化4箇方麵對橋位進行瞭深入比選。分析結果認為:工程河段具備建橋的宏觀河勢條件;十二圩河段較為穩定,十三圩河段次之,西界港河段變化較大。綜閤攷慮岸線資源利用,推薦十三圩橋位方案,研究成果可為擬建橋樑的設計與決策提供更為充分的技術依據。

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.
