摘　　要：宁波外滩大桥主桥采用主跨225 m的独塔四索面异型斜拉桥,全钢结构。以外滩大桥为工程背景,主要介绍了该桥的塔梁固结节点的受力特点、各主要荷载组合下的应力分布及传递路径等受力性能,其分析方法和结果可供类似工程参考。The main bridge of Ningbo Bund Bridge is 225-m single-pylon four-plane irregular cable-stayed bridge. It is the full-steel structure. Taking the Bund Bridge as the engineering background, the article mainly introduces the mechanical performance of pylon and beam consolidation joint of this bridge, the stress distribution under the main combined loads and the mechanical performance of transmitting route. The analysis method and result can be referred for the similar projects.
