摘要
随着建设技术的快速发展,中国铁路“走出去”的步伐在不断加速推进,国外铁路采用中国标准的项目也日益增多。本文结合相关国外铁路项目实施经验,归纳了开展国外铁路项目轨道设计时的主要注意事项,以供相关设计人员参考:(1)结合项目的特点及所在地国家的技术经济水平,充分考虑业主、咨询、承包商等建设各方的需求,采用适宜的轨道标准;(2)设计时要充分适应国外非标准化和注重计算推导分析的设计习惯;(3)在轨道类型、钢轨、轨枕和扣件、道床、无缝线路等轨道结构部件具体设计中,需要注意根据国外咨询要求、设计习惯、当地气候条件、养护维修技术水平等因素,开展一些非常规的设计。
With the rapid development of construction technology,the pace of China′s railway′going out′is continuing to accelerate,more and more foreign railway projects adopt Chinese standards.Based on the implementation experience of relevant foreign railway projects,this paper summarizes the main points for attention in the track design of foreign railway projects for the reference of relevant designers:(1)combining the characteristics of the project and the techno-economic level of the country where the project is located,appropriate track standards should be adopted according to fully considering the needs of owners,consultants,contractors and other construction partners;(2)the design should fully adapt to the foreign custom of non-standardization and emphasis on calculation and derivation analysis;(3)in the specific design of track type,rail,sleeper and fasteners,track bed,CWR and other track structure components,it is necessary to pay attention to some unconventional design according to foreign consulting requirements,design habits,local climate conditions,maintenance and repair technology level and other factors.
