调研了江苏省内三座跨江大桥2007—2010年的交通量和交通荷载状况，利用轮载谱分析货车交通量和交通荷载状况，并推荐了江苏省内货车轮载和典型轮载比例；分析江苏省内三座跨江大桥的货车超载情况并给出了超载比例较大的车型。研究成果为泰州大桥钢桥面铺装设计研究提供了有力支持。

The paper presents the traffic volume and loading of Yangtze River bridges in Jiangsu Province from 2007 to 2010. The results show that traffic volume is increasing along with the time. The traffic volume and loading of truck of Yangtze River Bridge are analyzed by wheel load spectrum. The paper gives the truck wheel load and typical wheel load ratio in Jiangsu Province. The overloading analysis show that overloading is serious in Yangtze River Bridges in Jiangsu Province.The research results is useful to the steel deck pavement design of Taizhou Bridge.
