复杂艰险山区铁路接触网设计技术思考

Reflections on the Design Techniques for the Railway Overhead Contact System in Challenging Mountain Areas

复杂艰险山区沿线地形地貌复杂、地质灾害频发、气候环境恶劣,接触网工程设计面临着诸多困难和挑战。本文对近年来开展的典型山区铁路(贵广、沪昆、成贵、成兰铁路等)进行了总结,基于接触网服役性能以及功能目标需求,分别从服役环境、工程接口、技术方案、标准规范等多个方面着手,理清接触网系统重难点问题及关键技术,提出有针对性的措施及解决方案,对存在问题展开深入思考并提出研究方向,为后续复杂艰险山区的接触网设计提供设计思路。

Challenging mountain areas are characterized by complicated terrain,frequent geological disasters,and harsh climates,leaving overhead contact system engineering design facing numerous difficulties and challenges.This paper reviewed typical mountain railways built in recent years(such as Guiyang-Guangzhou,Shanghai-Kunming,Chengdu-Guiyang,Chengdu-Lanzhou).Based on the performance of the overhead contact system and the functional objectives required,it approached the subject from several aspects including operational environment,engineering interfaces,technical plans,and standards and norms.The paper clarified critical technical and complex issues of the overhead contact system,proposing targeted measures and solutions.It offered deep thought into existing issues and suggested research directions,providing conceptual and design ideas for the subsequent design of overhead contact systems in complex and challenging mountain areas.
