摘　　要：随着高速公路、高速铁路网络的高速发展和日趋完善,高速公路与高速铁路的交叉设计越来越普遍。如何选择合理的交叉方案,减少相互影响,是亟需研究的重要课题。文章结合丹金高速公路与南沿江城际高速铁路交叉工程设计实践,对公铁工程建设条件进行分析,并从荷载设计、桥梁结构设计、附属工程设计等方面进行研究。研究认为,公路桥梁总体布置、跨径、净空及桥型的确定是工程设计的关键内容。With the rapid development and increasing improvement of network of expressways and high speed railways,the design of intersections between expressways and high speed railways is becoming increasingly common.How to choose the reasonable cross scheme and reduce mutual influence is an important issue that urgently needs to be studied.In combination with the design practice of the intersection project between Danjin expressway and intercity high speed railway along the river in the south,the construction conditions of highway and railway engineering are analyzed,and the research is made from the aspects of load design,bridge structure design,and ancillary engineering design and so on.The research shows that,determining the overall layout,span,clearance,and bridge type of highway bridges is the key content of engineering design.
