成渝中线高铁最长桥迎新进展
Xin Lang Cai Jing· 2026-01-27 18:56
龙泉特大桥东起成都市龙泉驿区洛带镇,西至成华区龙潭街道,全长14公里,是成渝中线高铁全线最长的桥梁。在跨越成华区新龙石路时,需 同时满足桥下道路通行净空和桥梁接入蜀安隧道的条件。受此影响,桥址处线路纵坡按25‰设计逐步下坡,坡度变化显著。该段无法采用高铁 连续梁常用的普通箱梁或悬灌连续梁跨越,经综合比选,最终采用1孔72米系杆拱桥结构,配合高位落梁施工工艺,跨越既有市政道路。该桥 型兼具适应大跨度、梁体高度低的特点,可最大限度保证桥下通行净空,从而在不中断桥下交通的情况下完成梁体施工。 长江沿岸铁路集团四川有限公司王学生表示,此次落梁顺利完成,不仅为后续同类型桥梁施工提供了宝贵经验,也为全线铺架工作顺利推进创 造了条件。目前,成渝中线高铁四川段建设正稳步推进,全线隧道已贯通25座,桥梁已合龙47座,工程已全面进入站房、"四电"工程及无砟轨 道施工的关键阶段。 成都日报锦观新闻记者 陈煦阳 受访单位供图 成渝中线高铁最长桥迎新进展 记者从长江沿岸铁路集团四川有限公司获悉,1月26日,经过150个小时的落梁作业,成都至重庆高速铁路(简称成渝中线高铁)龙泉特大桥 6000吨系杆拱桥平稳落位于桥墩之上,标志着成渝中线 ...
