“XXXXXL196”中国首条磁浮XXXXXL196市域(郊)铁路开工 预计2029年建成

  中新XXXXXL196社长沙11月11日电 XXXXXL196(付敬懿)中国首条磁浮市域(郊)铁路、湖南省首条市域轨道线——长沙至浏阳磁浮快线工程(简称“长浏快线”)11日正式开工,线路全长48.73公里,采用一次性规划、分段实施,总投资约182.75亿元人民币,最高设计时速为160公里,预计2029年建成通车。

  长浏快线由现有的长XXXXXL196沙磁浮快线东延线终点T3航站楼引出,全线共新建车站12座,土建预留3座高架站,规划预留2座高架站。项目分两期建设,目前开工的一期工程将建设黄花机场至集里段,线路长度39.52公里,设站10座。

  长浏快线建成后,将与中国首条具有完全自主知识产权的中低速磁浮——长沙磁浮线贯通运营,进一步推动长株潭都市圈与湘赣边区域协调发展。早在2023年1月,作为长株潭都市圈多层次轨道交通规划涵盖项目的长浏快线,就已获中国国家发展和改革委员会审核同意实施。

  长浏快线利用快速磁浮爬坡能力强、曲线半径小、低振动、低噪音优势,使得选线更为灵活,既可减少地下线比例又能避免高架敷设对沿线的影响,进一步降低工程投资,拓展磁浮应用场景。其设计时速160公里,是目前全球设计速度最高的常导短定子快速磁浮线路。

  此外,为持续推动磁浮技术更新迭代,占领技术高地,引领行业发展,该线预留未来开展时速200公里的试验条件,为快速磁浮进一步提高运行速度,应用于城际等更大空间应用场景预留了科研基础。

  作为国家批复的第四个国家级都市圈,长株潭都市圈目前正谋划推进三条市域城际快线,除了长浏快线,还有长宁快线、长株快线,均为磁浮制式。全新的长宁快线,编号定为S3,力争年内具备开工条件。长株快线,编号定为S4,仍在完善可行性研究报告阶段。(完)
