摘　　要：国际项目中道路建设设计规范的选择具有较大自由度。以肯尼亚内罗毕快速路为例,介绍了中国公路及城市道路标准、美国AASHTO、英国DMRB、法国标准、肯尼亚标准中关于公路横断面各组件的定义及要求,概括了多国(地区)规范对比融合在该项目中的应用分析,以及采用各国(地区)规范中最小或偏小横断面宽度的经济性对比分析。横断面组成及宽度控制公路建设项目的工程规模及建设难度,规范的融合研究可为海外项目商务和技术决策提供参考。The application of design codes and standards in international projects is usually flexible.In the paper,relying on the Nairobi Expressway Project in Kenya,the definitions and requirements of cross section elements are introduced as per the Chinese highway and urban road standards,American AASHTO,British DMRB,French standards,and Kenyan standards.The comparisons and integration of various specifications are concluded,and comprehensive analysis of adopting the most economical cross-sectional widths using different national standards is carried out,and the impact of cross section composition and width on the project scope and construction organization is analyzed.The study of various national specifications can provide reference for decision-makings in terms of commercial and technical perspectives.
