“俄罗斯人与动物XXXX”揭惠铁路第俄罗斯人与动物XXXX一长隧百吉岭隧道贯通

  中新俄罗斯人与动物XXXX网揭阳11月15日电 (俄罗斯人与动物XXXX郭军 郭遥 韦相宇)11月15日,由广东省铁投集团所属揭惠铁路公司投资建设、中铁二十五局承建的揭阳至惠来铁路(以下简称“揭惠铁路”)全线第一长隧——百吉岭隧道顺利贯通,标志着工程建设打通关键节点,为项目2025年底建成创造有利条件。

  揭惠铁路正线全长88.66公里,设计为时速160公里客货两用铁路,项目线路起至梅汕铁路揭阳站,经揭东区、揭阳产业园、揭西县、普宁市、惠来县,终至汕汕铁路惠来站。中铁二十五局承建的站前1标段长约11.18公里,桥隧比达99.57%,其中,全长9814.54米的百吉岭隧道为全线控制性工程、最长隧道。

  据中铁二十五局项目技术负责人曹佳庆介绍,百吉岭隧道地质条件极其复杂,需下穿森林公园环境敏感区,且施工区域山势起伏大、毗邻众多水库,隧道掘进先后穿越断层破碎带4次、侵入岩接触带4处、破碎区5处、强富水区9段,施工安全风险极高。

  为此,项目建设者通过瞬变电磁、超前水平钻孔、孔内成像等超前地质预报手段,探明前方围岩及富水情况,有针对性调整工法及措施,确保施工安全。同时,坚持科技赋能,应用安全管理信息化平台,实时监测人员活动轨迹和隧道进度安全,提高施工管理的科学化和精准化,保障了掌子面的安全顺利掘进。

  据悉,揭惠铁路是广东省综合交通运输体系“十四五”发展规划的一项重点工程,开通后将与梅汕、广梅汕、杭深、汕汕等铁路连接,成为揭阳港货物外运及沿线居民便捷出行的重要路径。项目建成后,将进一步满足揭阳港区集疏运的需求,对推动交通强国等国家战略深入实施落地,完善粤东地区互联互通城际铁路网建设,推动沿线地区经济社会发展具有重要意义。(完)
