摘　　要：宝鸡市陈仓渭河大桥工程道路总长1.9 km,由南向北与总计八条道路相交。交通方案总体设计时,分清主次,近远结合,避免了多路交叉带来的交通混乱问题。河道内主桥为7×60 m预应力混凝土变截面连续梁,通过景观设计,将具有“秦风古韵”特色的建筑设计引入现代桥梁中,古今结合,彰显了中国悠久文明历史。桥梁设计采用多种技术措施,解决了大跨径长联桥带来的施工和运营问题。通过合理结构设计,解决了国内实际工程中少见的桥梁跨中引出匝道岔口复杂问题,可供类似工程借鉴。The total length of the road in Baoji City Chencang Weihe Bridge Project is 1.9 km.The road is intersected with 8 roads from south to north.In the overall design of the traffic scheme,the primary and secondary roads are distinguished,and the short term and the long term are combined to avoid the traffic confusion caused by the multiple road intersections.The main bridge in the river channel is a 7×60m prestressed concrete variable cross-section continuous beam bridge.Through the landscape design,the architectural design with the features of"Qin Dynasty"is introduced into the modern bridges.The combination of the ancient and modern features shows the long history of civilization in China.The multiple technical measures taken in the bridge design solve the construction and operation problems caused by long-span and long-connected bridges.And the reasonable structural design solves the complex problems of ramp forks led from the bridge spans,which are rare in domestic projects,and can be referred for the similar projects.
