摘　　要：研究目的:爪哇岛与苏门答腊岛之间的巽他海峡主要靠渡船运输,因此建设一座巽他海峡大桥将促进这两个岛(尤其是万丹省和楠榜省的周围区域)的经济发展,它也是印度尼西亚经济建设总体规划中确定的最大基础设施项目,备受印度尼西亚国内外的关注。成为了论证该桥建设的可行性,提出了三条桥梁路线方案,通过海洋测深学研究和海底剖面的绘制,选择了最佳桥位路线;在最佳路线中,设计了单层和双层两种桥面方案,通过两种软件的有限元分析和模型风洞试验,确定桥面方案。研究结论:通过研究与分析得出:(1)巽他海峡大桥的概念设计选择了从安亚到巴果亥尼的总长29.5 km的路线。(2)巽他海峡大桥包括两座超长跨桥,跨径分别为2 016 m和1224 m。(3)两座超长跨桥的基础都采用强度60 MPa的预制混凝土沉箱。(4)根据横剖面模型风洞试验结果,两座超长跨桥选择了双层桥面。(5)在未来的可行性研究及将来的详细设计中,巽他海峡大桥的气动性能仍会成为研究的一个关键目标。Research purpose:The Sunda Strait between Java Island and Sumatra Island in the Western part of Indonesia is still served mainly by sea transport,particularly for goods that are mostly served by ferries crossing the strait.So constructing a Sunda Strait bridge will boost the economic development of the two islands,in particular the surrounding regions such as Banten Province and Lampung Province.The bridge is the biggest fundamental project determined by national overall economic plan of Indonesia,and becomes one of projects focused at home and abroad.To verify the feasibility of the bridge,three alternative routes were proposed.Based on the 2013 Sunda Strait sea bottom profiling and bathymetry study,the best alternative was chosen as the most favorable route for Sunda Strait bridge.On top of that,two alternatives of bridge deck were proposed for the ultra long-span bridges,i,e,double level deck and single level deck.Selection of the bridge deck model was done by performing the aerodynamic study though wind tunnel test and by carrying out simulations with FEM software.Research conclusions:①The conceptual design of Sunda Strait Brdge has chosen a bridge route from Anyer to Bakauheni with a total length of 29.5 km.②The bridge consists of two ultra long-span bridges,with spans of 2 016 meters,and 1 224 meters,respectively.③Foundations of both ultra long-span bridges are proposed to use 60 MPa precast concrete caisson.④Based on the sectional model wind tunnel testing result,the double level deck type is chosen for the ultra long-span bridges.⑤The aerodynamic performance of Sunda Strait Bridge will still be a key research subject at the further feasibility study or even in the future detailed design stage.
