中新网揭阳8月11日电 (记者 蔡敏婕)揭惠铁路全线槽箱组合混凝土梁11日浇筑完成,为下一步跨梅汕高铁转体作业奠定基础。
揭(阳至)惠(来)铁路是广东省“十四五”规划的一项重点工程,位于揭阳市境内,起自梅汕铁路揭阳站,止于在建汕汕铁路惠来站,正线全长约88.7公里,设计时速160公里。

跨梅汕高铁特大桥全长约2978米,分别跨越梅汕高铁、畲龙铁路、揭普惠高速公路等。槽箱组合梁位于揭惠铁路跨梅汕高铁特大桥38、39、40号墩之间,跨度为72米+72米,主梁全长145.2米(含两侧梁端至边支座中心距离各0.6米),桥面净宽为7米。槽箱组合连续梁的施工需经过分步浇筑作业成形后,再转体横跨正在营运的梅汕高铁。这种结构及跨度为我国现有铁路桥梁首例,技术要求高,安全风险大。
中铁一局项目部总工何神彪介绍,为了降低桥梁建筑高度,满足跨越既有高铁路堑较宽、线路曲线半径较小结构抗扭要求,因此采用槽箱组合结构转体施工。
“这种结构及跨度为我国现有铁路桥梁首例,技术要求高,安全风险大。此次完成浇筑施工也为今后类似结构的设计和施工的相关科学研究提供依据和参考。”何神彪说。
槽箱组合连续梁从2025年12月17日开始分步浇筑,直到2026年8月11日浇筑完成。
揭惠铁路建成后将提升港口服务品质,带动临港产业聚集及地区港口经济发展,同时对完善粤东地区互联互通城际铁路网建设,推动周边地区深度融合发展,实现沿线地区高质量发展具有重要意义。(完)
