摘　　要：中山市板芙二桥主桥为独塔双索面不对称斜拉桥,跨径布置为(77+102)m,采用塔梁墩固结的结构形式,文中介绍了该桥的主梁、主塔、拉索及下部结构的设计情况。给出了静力计算的主要结果,通过动力计算得出该桥的振型、地震作用下动力性能以及稳定安全系数等,给出的参数选型是整体桥梁设计的关键。The main bridge of Banfu No.2 Bridge in Zhongshan is a single pylon with double cable planes, asymmetrically ca- ble-stayed bridge with the span arrangement at （77＋102） m. In the design, the pylon, main girder and pylon pier are rigidly built. In this paper, the design of the main girder, pylon, cable stays and sub-structure is detailed and the key results of static analysis are given. The bridge＇s mode of vibration, dynamic characteristics under seismic actions and buckling safety factor are derived by dynamic calculations and the given parameters are the key points for designing the complete bridge.
