摘　　要：铝合金桥梁建设在我国刚刚起步,面临诸多技术难题。大跨径钢-铝组合桥梁更是少之又少。依附实际工程项目,分析探索大跨径钢-铝组合桥梁设计方法,对结构变形、应力水平、自振频率和屈曲特性进行对比分析,探索大跨径钢-铝组合桥的优势与缺点。对铝合金桥梁设计、钢-铝组合桥梁设计以及开拓设计师的思维具有重大意义。The construction of aluminum-alloy bridges starts in China just now, and is faced with many technical difficulties. The long-span steel-aluminum composite bridge is even less. Based on the practical engineering projects, the article analyzes and discusses the design methods of long-span steel-aluminum composite bridge, compares and analyzes the structural deformation, stress level, natural vibration frequency and buckling characteristics, and discusses the advantages and disadvantages of long-span steel-aluminum composite bridge, which have the significance for the design of aluminum-alloy bridge, design of steel-aluminum composite bridge and development of designer thought.
