摘要:
沪通长江大桥为4线铁路与6车道高速公路合建桥，其天生港专用航道设计采用主跨336 m的钢性梁柔性拱桥结构形式，基础建设较为复杂。文章以此桥为研究对象，根据建设条件、主桥基础特点等出发，从结构受力特性、经济性能、施工便利性等方面对钻孔桩基础和沉井基础方案进行综合方案比选，最终推荐采用桩基础方案，可为类似建设条件的桥梁结构提供参考。
Abstract:
Hutong Yangtze river bridge is a bridge for 4-line railway and 6-lane expressway. Its Tianshenggang special channel design adopts the structural form of steel beam flexible arch bridge with a main span of 336m, and its infrastructure construction is relatively complex. Taking this bridge as the research object, this paper compares and selects comprehensive schemes of bored pile foundation and caisson foundation from the aspects of structural stress characteristics, economic performance and construction convenience according to construction conditions and main bridge foundation characteristics, and finally recommends the adoption of pile foundation scheme, which can provide reference for bridge structures with similar construction conditions.
