摘　　要：随着我国“十四五”交通规划推进,既有铁路扩能改造成为提升路网效能的关键。佳富铁路作为京津冀至东北的交通要道,面临运能紧张和标准低的问题。文章针对佳富线K0+000—K12+000段,分析了既有铁路的概况、问题及改造原则,提出兴国村北双绕方案为推荐方案。该方案双绕消除小曲线半径,提升速度、降低成本、投资适中、经济可行。该研究为佳富铁路未来建设扩能提供支持,也为其他铁路改造提供参考,对推动我国铁路事业持续发展具有重要意义。With China’s“14th Five-Year Plan”transportation planning to promote the expansion of existing railroads has become the key to enhance the effectiveness of the road network.Jiafu Railway as Beijing-Tianjin-Hebei to the northeast of the main road,facing capacity constraints and low standards.In this paper,the K0+000 to K12+000 section of Jiafu line is analyzed,and the general situation,problems and transformation principles are analyzed,and the double-rounding scheme north of Xingguo Village is proposed as the recommended scheme.The program double-rounding eliminates the small curve radius,improves the speed,reduces the cost,moderate investment,economic feasibility.The study provides support for the future of Jiafu Railway,and also provides reference for the transformation of other railroads,which is of great significance in promoting the sustainable development of China’s railroad industry.
