| 摘 要： | 上海崇明越江通道长江大桥工程主通航孔桥为一座主跨730 m的双塔双索面分离式钢箱梁斜拉桥,桥面上除公路交通外还有轨道交通,无论结构形式还是气动外形都比较新颖和复杂.通过节段模型试验、大尺度涡振试验、气弹模型试验和拉索人工降雨试验等各种现代风洞试验方法,从静风稳定性、颤振稳定性、涡激共振性能和拉索风雨激振性能等方面检验主通航孔桥斜拉桥结构的抗风稳定性能.

| Abstract: | The main navigable span bridge of the Changjiang River Bridge,Shanghai Chongming River Crossing is a separated steel box girder cable-stayed bridge with a main span 730 m and with double pylons and double cable planes.In addition to the highway lanes arranged on the deck of the bridge,the light rail transit is arranged as well.Of the bridge,either the structural type or the aerodynamic profile is rather novel and complicated.In this paper,the wind resistant stability of the bridge is checked from aspect of ... |
