摘　　要：随着人们对交通和周边居住环境要求的提升,快速、低影响施工在城市工程建设中的应用越来越多。多梁式钢-混凝土组合梁桥在城市桥梁建设中体现出施工周期短、施工阶段对交通影响小、工厂化生产、造价适中、能与标准段预制结构匹配等优势,可保证全线景观统一,有效缓解施工与交通冲突的矛盾,进而在城市高架桥中得到应用,是城市桥梁中较为新颖的结构形式。通过对钢-混组合梁采用多种计算方法进行对比分析,结果表明多梁式钢-混凝土组合梁桥受力性能良好,在城市高架中具有较强的推广价值。With the improvement of people's demand for traffic and surrounding living environment,the rapid and low-impact construction is more and more used in urban engineering construction.The multi-beam steel-concrete composite beam bridges have the advantages of short construction period,low impact on traffic,factory production,moderate cost,and ability to match the precast construction of standard section in the construction of urban bridges,which can ensure the uniformity of the whole landscape,effectively alleviate the contradiction between construction and traffic conflict,and then be used in the urban viaduct,and is a relatively new structural form of urban bridges.Through the comparison and analysis on various calculation methods of steel-concrete composite beams,the results show that the multi-beam steel-concrete composite beam bridge has the good stress performance and has the strong popularization value in urban viaduct.
