摘要： 既有铁路复线化是铁路建设发展的重要领域，传统范式大多沿既有通道增建二线。研究提出 一种基于区域协调发展战略的广域路径建模和比选方法，并以精伊霍铁路为例进行实证。在剖析项 目必要性、紧迫性及原方案局限性的基础上，以广度优先搜索和“橡皮筋”算法构建广域路径选择 模型和比选方案，并从技术经济、工程实施、运营组织和综合效益4 个维度共16 项指标开展综合比 较，进而提出近期可实施的优化方案及建议。研究表明：1)在存量优化背景下，铁路建设项目稀缺 性日益凸显，基于区域协调发展战略的广域路径探索方法有助于改善单一工程视角的局限，为铁路 复线化实践提供新思路；2)精伊霍铁路增建二线工程若采用博乐市至伊宁市直通线的推荐方案，在 技术经济性、存量资源综合利用、降本增效和区域发展引领等方面，较原方案均具有显著优势和战 略意义，下一步应重点针对天山穿越段开展工程深化论证。

Abstract： Double-tracking existing railways is an important component of railway development. However, the traditional approach has largely involved constructing a second track along the existing corridor. This paper proposes a broad-area routing modeling and comparison method based on the regional coordinated development strategy and conducts an empirical analysis using the Jinghe-Yining-Huoerguosi Railway as a case study. After examining the project necessity, urgency, and limitations of the original plan, the paper employs a breadth-first search and a“rubber band”algorithm to develop a broad-area routing model and comparison schemes, and performs a comprehensive comparison using sixteen indicators in four dimensions: technical and economic performance, engineering implementation, operational organization, and overall benefits. The paper presents optimization plans and recommendations for near- term implementation. The study demonstrates that: (1) in the context of stock optimization, railway construction projects have become increasingly scarce, and a braod-area routing approach based on the regional coordinated development strategy helps address the limitation of a single- project perspective, offering new insights for double-tracking railways; (2) for the addition of a second track to the Jinghe-Yining-Huoerguosi Railway, adopting the recommended direct line from Bole to Yining would provide significant advantages and strategic values over the original plan in terms of technical and economic performance, integrated utilization of existing resources, cost reduction and efficiency enhancement, and support for regional development. Subsequent efforts should prioritize in-depth engineering demonstration of the Tianshan Mountain's crossing section.
