摘　　要：城市高架桥一般是在已建道路上改扩建而来,常常会有在地面跨河桥上方新建主线高架跨河桥的情况,该类桥梁不是常规的跨河桥,具有一些特殊性,主线高架跨河桥桥型方案会受到地面现状跨河桥的一些影响。文章通过对设计跨河高架桥方案时需要重点考虑的关键因素进行分析研究及总结,为以后该类城市高架桥的设计提供一些借鉴和参考。Urban viaducts are generally renovated and expanded on the existing roads. There are often new mainline viaduct bridges above the ground-crossing bridges. This type of bridge is not a conventional bridge across the river. It has some special features. The bridge type scheme will be affected by the existing cross-river bridges on the ground. This paper analyzes and summarizes the key factors that need to be considered when designing this type of bridge scheme, and provides some reference for the design of such urban viaducts in the future.
