摘　　要：基于武汉市白沙洲公铁复线桥接线工程,从现状交通体系梳理,功能定位分析,通道规模论证,过江交通组织模式、两岸交通疏解体系和现状接线系统改造等方面,对接线方案设计的要点进行分析和总结。研究两岸接线作为新建复线桥与两岸现状交通系统的衔接纽带,重塑一个更加高效的过江交通体系。这为其他类似复线桥的总体方案设计提供借鉴、参考。Based on the connection project of Wuhan Baishazhou highway&railway doubletrack bridge,the key points of the connection scheme design are analyzed&summarized from the aspects of sorting out the current traffic system,functional positioning analysis,demonstration of channel scale,river crossing traffic organization mode,cross-bank traffic relief system and transformation of the current connection system.Study the cross-bank connection as the link between the new double-track bridge&the existing traffic system of the both banks,and reshape a more efficient cross-river traffic system.It provides a reference for the overall design of other similar double-track bridges.
