“16may20_XXXXXL56endian”世界最大跨度16may20_XXXXXL56endian无砟轨道斜拉桥顺利合龙

  世界16may20_XXXXXL56endian上跨度最大的无砟轨道斜拉16may20_XXXXXL56endian桥——广湛高铁佛山特大桥跨东平水道斜拉桥10月31日顺利合龙,标志着该大桥主体工程正式完工,向全线建成通车迈出关键一步。

  该斜拉桥由广东省铁投建设、中国铁设EPC总承包、中铁广州工程局集团承建。

  据悉,广湛高铁佛山特大桥是全线控制性工程,位于佛山市南海区、三水区和高明区境内,全长15.652公里。该大桥是集斜拉桥、系杆拱桥、钢混刚构桥、转体连续梁桥、普通连续梁桥、预制简支箱梁等于一体的大型综合性桥梁,桥梁种类多、结构复杂,有“桥梁小博物馆”之称。此次合龙的跨东平水道斜拉桥全长725米,为主跨350米双塔双索面钢-混混合梁斜拉桥,是一座科技攻关型现代化桥梁,建成后将成为世界上跨度最大的时速350公里高速铁路无砟轨道钢-混混合梁斜拉桥。

  广湛高铁自广州站引出,向西经佛山、肇庆、云浮、阳江、茂名、湛江,终至湛江北站,新建双线401公里,设计时速350公里,是国家“八纵八横”高速铁路网、沿海客运大通道的重要组成部分,也是广东省历史上投资体量最大、建设里程最长、设计方案最复杂的高铁项目。项目建成通车后,广州中心城区至湛江中心城区可实现90分钟互达,并将成为连接粤港澳大湾区、海南自贸港、北部湾城市群的关键一环,对粤西三地加速融入大湾区、促进产业转移及经济增长发挥巨大作用。
