多孔径超长晋陕黄河特大桥桥位比选研究
|
摘要
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。
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.
