摘要
研究目的:通过亚吉铁路的工程建设实践,从分析亚吉铁路沿线的国情、经济发展水平、沿线自然地理特征、施工技术现状和设计方案完善过程入手,分析了亚吉铁路技术标准和工程措施的形成基础和适应条件,形成的埃塞俄比亚铁路设计标准和技术系统过程。参照中国铁路Ⅱ级的标准,以“技术标准属地化、工程措施实用化、生态环境可持续化”的理念整理出了该条铁路的技术标准;以经济性分析为核心,总结出该标准在当地的工程实践和经济发展中不断完善和创新的经验;提出中国铁路技术标准在亚吉铁路中的经济性分析。研究结论:(1)在亚吉铁路建设中,要以当地经济条件、技术现状、生态环境、可用资源等支撑能力为基础;(2)埃塞俄比亚铁路建设应与经济规划、生产布局相适应;支撑铁路运营的运输、动力、人力等上下游产业链必须协同发展;(3)埃塞俄比亚铁路技术标准需要在当地的工程实践和经济发展中不断完善和创新;(4)本文研究可为中国铁路技术标准走出去的工程实践提供一定的指导作用。
Research purposes:Through the engineering construction practice of the Ethiopia-Djibouti Railway,this study begins by analyzing the national conditions,economic development levels,natural geographical features along the railway line,current status of construction technology,and the process of refining design schemes.It analyzes the formation basis and adaptation conditions of the Ethiopia-Djibouti Railway's technical standards and engineering measures,as well as the process of forming Ethiopian railway design standards and technical systems.Drawing from Chinese railway GradeⅡstandards,the technical standards for this railway are organized with the concept of"localization of technical standards,practicality of engineering measures,and sustainability of the ecological environment".With economic analysis as the core,this study summarizes the continuous improvement and innovation of these standards in local engineering practices and economic development.It proposes an economic analysis of Chinese railway technical standards on the Ethiopia-Djibouti Railway.Research conclusions:(1)The construction of the Addis Ababa-Djibouti Railway should be based on local economic conditions,technical status,ecological environment,and resource availability.(2)The construction of the Ethiopian railway should align with economic and production layout;the upstream and industries supporting railway operations,such as transportation,power,and human resources,must develop synergistically.(3)Ethiopian railway technical standards need continuous improvement and innovation within local engineering practices and economic development.(4)This study can guide the practice of applying Chinese railway technical standards internationally.
