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。
The main navigable bridge of Shanghai Chongming Yangtze River Channel Yangtze River Bridge Project is a cable-stayed bridge with double-tower double cable plane and separate steel box girder with a main span of 730 m. There are also rail transportation on the bridge surface in addition to the road traffic, regardless of the structure or the aerodynamic shape Are relatively new and complex. Through various modern wind tunnel test methods such as segment model test, large-scale vortex vibration test, aeroelastic model test and artificial cable rain test, the stability of static wind, flutter stability, vortex-induced resonance, Vibration performance and other aspects of the main navigation hole bridge cable-stayed bridge structure of the wind stability.
