研究目的：晋陕黄河特大桥是大西铁路客运专线“三桥一隧”重点工程之一，桥位选址的受控因素众多，特别是水文、环保、军事设施尤为控制，就如何达到各个方面的综合最优，本文从桥梁跨度、主桥桥式及桥位方案等方面进行详尽分析比选，最终确定技术可行、经济合理的桥位方案。
研究结论：（1）通过对晋陕黄河特大桥桥位进行多方案比选，最终确定了中桥桥位推荐方案，该方案虽对黄河排洪有一定影响，但所经地区无不良地质，桥隧所占比重最小，对湿地森林公园影响最小，且工程投资最省；（2）该研究成果已在2014年7月1日开通的大西客专晋陕黄河特大桥上得到全面应用，可为今后我国在大江大河上需要修建相似桥梁工程提供设计参考。
Abstract：Research purposes： The Shanxi-Shaanxi Yellow River Super Large Bridge is one of the major projects in Datong-Xi′an Railway. Bridge location of this super large bridge is controlled by many factors, especially hydrology, environmental protection, and military installations. In order to make the comprehensive optimum scheme, this paper makes a elaborate analysis and comparison between bridge location and the style of main bridge, finally obtains a technically feasible, economically reasonable bridge location scheme.
Research conclusions：(1) After making a elaborate analysis and comparison between bridge location schemes, a reasonable recommended proposal is obtained which is technically feasible, economically reasonable, and easy to implement. (2) The achievement has been applied to Shanxi-Shaanxi Yellow River Super Large Bridge in Datong-Xi′an passenger dedicated line on July 7, 2014 and can provide reference for similar bridge constructions
