摘　　要：新建广州至汕尾高速铁路跨越深汕西高速公路,高速铁路与高速公路夹角仅为26°。为了确定高速铁路跨越高速公路桥梁的合理设计方案,从功能要求、受力性能、轨道平顺性、经济性能、施工对高速公路的干扰、运营期维养等方面进行综合比选。研究结果表明,主跨160m的拱承斜拉桥为该桥的合理桥式方案。通过结构体系、拱塔轴线线形、拱塔截面型式等方面的研究,确定了拱承斜拉桥的合理结构方案。Newly-built Guangzhou-Shanweihigh-speedrailway crosses over western section of Shenzhen-Shantou highway.The angle between the high-speedrailway and the highway is only 26°,In order to determine the most reasonable design scheme for high-speed railway bridge Spanning Highway,a comprehensive comparison was made fromfunctional requirements,mechanical performance,track smoothness,cost,interference of construction on the highwayandmaintenance during operation,The research results indicates that the arch-support cable-stayed bridge with a main span of 160m is the reasonable bridge type scheme for the bridge.Reasonable structural scheme for arch supported cable-stayed bridge was determined by research on structural system,arch tower axis alignment,and arch tower section type.
