摘　　要：为在海外工程中合理运用欧洲规范进行钢筋混凝土桥设计与计算,以刚果(布)国家1号公路二期工程钢筋混凝土桥为例,介绍采用欧洲规范进行钢筋混凝土桥设计的总体思路、结构型式、结构计算等内容。桥梁参考工程所在地实际情况、一期工程设计文件桥型的继承、标准化设计、法国规范及其工程习惯和施工方特长等进行设计;采用线弹性分析方法进行结构分析,验算结果均符合规范要求。对比发现,欧洲规范与中国规范差异较大,设计者在运用欧洲规范指导设计时须具有扎实的理论和计算功底。For rational application of Eurocode in the design and calculation of reinforced con- crete bridge in overseas project, the general idea, structural type and structural calculation relat- ed to the design of such type of bridge directed by the Eurocode is introduced based on the exam- ple of the reinforced concrete bridge of No. 1 national highway phase Ⅱ project in the Republic of Congo. The bridge was designed taking account of the practical condition of the project location, the bridge type in the design documents of the phase I project, standard design, the French Code and custom of engineering and the specialty of the construction company. The linear elastic analy- sis was adopted to conduct structural analysis and all the results of checking computation met the code requirements. Results of Comparison show that there is a big difference between Eurocode and Chinese Code and designers should have sound basis of theory and calculation when using Eu- rocode to guide design.
