摘　　要：互通立交作为一种高效的交通设施在城市交通中扮演着重要角色,是实现不同道路间交通流转换的重要节点,随着现代化城市发展,有些既有城市立交无法满足日益增长的交通需求,实践表明,通过对既有桥梁进行改扩建以完善其通行功能的设计方案,虽涉及新、旧桥的接驳等难点,但它往往能节省造价、充分利用既有桥的价值,是一种值得研究和推广的城市立交桥设计方法。As an efficient transportation facility,interchange plays an important role in urban traffic,it is an important node for traffic flow transformation between different roads.With the development of modern cities,some existing interchanges cannot meet the increasing traffic demand,practice shows that the design scheme to improve and expand the existing bridge involves the difficulties of connection between new and old bridges and others,but it often saves money and make full use of the value of the existing bridges,which is a design method for urban overpass to research and promote worthily.
